Security Issues

Recently, Wireless Mesh Network is deliberated as a significant technology due to its self-healing, self-configuring and self-organizing features. The Multi-hop nature of WMN nodes has the potential to forward the data traffic to their intended destination node without the involvement of source node. One of the factors that impact the WMN performance is secure communication process. Various secure authentication mechanisms have been projected however, authentication delay and communication overheads are listed as the main security issues of these approaches. In this article, an efficient and fast authentication protocol have been proposed to reduce the response time, computation overhead during encryption/decryption process of the routing messages. Further various simulations with erratic nodes have been conducted to endorse the enhancement of proposed solution against existing protocols. Moreover, performance comparison between existing and proposed schemes have been analyzed in detail showing that proposed approach has achieved better outcome against convinced consequences.

Frequent Problem

[Id]Koneksi internet yang sering terputus merupakan masalah yang sering dijumpai oleh orang-orang hampir di seluruh dunia. Apalagi dalam kehidupan sehari-hari, manusia memiliki ketergantungan yang tinggi terhadap internet. Sebuah topologi yang dinamakan mesh dapat digunakan untuk membangun sebuah jaringan. Topologi mesh memiliki dua karakteristik yaitu self-healing dan self-configuring. Kedua karakteristik tersebut dapat diterapkan dalam menangani masalah internet terputus. Kemudian, penggunaan ponsel cerdas berbasis Android kian meningkat, terutama untuk di Indonesia. Dengan berkembangnya ponsel cerdas berbasis Android yang begitu pesat, maka dibangun sebuah aplikasi pada ponsel cerdas berbasis Android untuk menangani masalah internet terputus dengan menerapkan karakteristik topologi mesh, yaitu self-healing dan self-configuring. Aplikasi dapat menampilkan informasi yang berhubungan dengan jaringan dan juga dapat berkomunikasi dengan ponsel lain yang terhubung melalui hotspot dengan menggunakan pemrograman socket. Pada penelitian ini, Aplikasi berhasil dibangun menggunakan bahasa Java untuk ponsel cerdas berbasis Android. Teknologi Wi-Fi dan hotspot digunakan untuk menghubungkan ponsel ke internet. Pengguna dapat melihat informasi Service Set Identifier (SSID) yang diurutkan berdasarkan kekuatan sinyal, dan aplikasi akan otomatis menghubungkan dengan SSID yang memiliki kekuatan paling besar. Setelah terhubung dengan internet, pengguna dapat melihat siapa saja yang terhubung dalam satu hotspot. Dan juga dapat melakukan sharing internet terhadap ponsel lain yang terhubung dalam satu jaringan.[En]Internet disconnections is a frequent problem encountered by people almost all over the world. Moreover in everyday life, people have a high dependence on the Internet. Mesh topology can be used to build a network. Mesh topology has two characteristics that is self-healing and self-configuring. Both of these characteristics can be applied in dealing with interrupted internet connection. Then, the growth of using Android-based smart phones is increasing, especially in Indonesia. With the development of Android based smartphone, we created an application on smart phone to address the issue of internet disconnection by applying the characteristics of mesh topology, which is self-healing and self-configuring. Applications can display information related to the network and can also communicate with other phones that are connected via hotspot using socket programming. In this research, application was built using Java for Android-based smartphones. Wi-Fi and Hotspot are used to connect the smartphone to the Internet. Users can see the SSID information sorted based on signal strength, and the application will automatically connect to the SSID that have highest signal strength. Once smartphone connected to the Internet, users can see who is connected in a hotspot. And also can share the internet to another phone connected in a network.Keywords :Android, Mesh Network, Wifi

Wimax Mesh Network

WiMAX based on IEEE std 802.16 is believed one of the important technologies of 4G. It aims to provide high-speed access over distance of several to tens kilometers. In IEEE std 802.16-2004, WiMAX defines an optional mesh mode, with which multi-hop, multi-route, self-organizing and self-healing communications can be achieved in metropolitan-level areas. This chapter presents medium access control (MAC) protocol of WiMAX mesh mode, on frame structure, network configuration, network entry, and scheduling algorithms. It also summaries the most recent progress on data slots resource scheduling and allocation algorithms. Finally, an application example of using WiMAX mesh network for high-speed and low-cost maritime communications is also presented in this chapter.

Recently, Wireless Mesh Network is deliberated as a significant technology due to its self-healing and self-organizing characteristics. In WMN, data is forwarded through multiple hops to the destination node. One of the factors that impact the network performance is the secure communication delay. An authentication technique having significant delay may enhance the possibility of several security threats. A number of authentication protocols have been proposed in the literature but if existing practices are deliberated then to optimize one of the constraint other parameters are affected radically. In this manuscript, a Diffie-Hellman elliptic curve technique is used over WMN which reduces latency and computational overhead issues. Further to prove the integrity of proposed work, the performance is measured theoretically and analyzed experimentally over ns2 simulator.

Wireless Mesh

Wireless telemedicine using GSM and GPRS technologies can only provide low bandwidth connections, which makes it difficult to transmit images and video. Satellite or 3G wireless transmission provides greater bandwidth, but the running costs are high. Wireless networks (WLANs) appear promising, since they can supply high bandwidth at low cost. However, the WLAN technology has limitations, such as coverage. A new wireless networking technology named the wireless mesh network (WMN) overcomes some of the limitations of the WLAN. A WMN combines the characteristics of both a WLAN and ad hoc networks, thus forming an intelligent, large scale and broadband wireless network. These features are attractive for telemedicine and telecare because of the ability to provide data, voice and video communications over a large area. One successful wireless telemedicine project which uses wireless mesh technology is the Emergency Room Link (ER-LINK) in Tucson, Arizona, USA. There are three key characteristics of a WMN: self-organization, including self-management and self-healing; dynamic changes in network topology; and scalability. What we may now see is a shift from mobile communication and satellite systems for wireless telemedicine to the use of wireless networks based on mesh technology, since the latter are very attractive in terms of cost, reliability and speed.
