Secure Routing Protocols

A freely moving nodes forming as group to communicate among themselves are called as Mobile AdHoc Networks (MANET). Many applications are choosing this MANET for effective commutation due to its flexible nature in forming a network. But due to its openness characteristics it is posing many security challenges. As it has highly dynamic network topology security for routing is playing a major role. We have very good routing protocols for route discovery as well as for transporting data packers but most of them lack the feature of security like AODV. In this paper we are studying the basic protocol AODV and identify how it can be made secure. We are studying a protocol S-AODV which is a security extension of AODV which is called Secure AODV (S-AODV) and we are studying enhanced version of S-AODV routing protocol a Adaptive Secure AODV (A-SAODV). Finally we have described about the parameter to be taken for performance evaluation of different secure routing protocols

Usually, the nodes in Mobile Adhoc Networks (MANET) are bounded with the limited power resources to interact with each other nodes without any backbone infrastructures. As a result, an allocation of unbalanced traffic among nodes may increase the power dissipation in the overloaded nodes and path failures that degrade the network lifetime. To tackle this problem, an on-demand Power and LoadAware (PLA) multipath node-disjoint source routing scheme was proposed based on the Dynamic Source Routing (DSR) protocol that uses a new cost function to determine the multiple nodedisjoint power and select the load-aware optimal paths to their destinations. However, this protocol was affected by control overhead and the reliable packet delivery was also not effective. Hence in this article, Power and Load-aware i.e., Utility-Aware Reliable Opportunistic Routing (UAROR) protocol is proposed to enhance the efficiency and reliability of the routing protocol. In this protocol, topology control and link lifetime prediction algorithms are integrated into the PLA algorithm to predict the effect of the node mobility on routing performance. The link prediction algorithm considers both mobility speed and direction for improving the accuracy. As well, an opportunistic topology control algorithm uses packet delivery ratio to maintain the node’s stability. Moreover, Utility-Aware Enhanced ROR (UAEROR) protocol is proposed to improve the node’s stability and reduce the control overhead by employing the neighbor detection algorithm that uses degree and reachability of nodes. Finally, the simulation results show that the effectiveness of the proposed protocol compared to the existing protocol in terms of throughput, end-to-end delay, packet delivery ratio, network lifetime, energy consumption and control overhead

<p>Ensuring collateral is the most substantial snag in Mobile Adhoc Networks which crash the efficacy of the network. Without regard to all different networks, the Mobile Adhoc network is stuffed with more safety hindrances and the Adhoc on Demand Vector Routing Protocol is more comprehensively utilized protocol in MANETS. This type of network is more exposed to assorted number of attacks and among those, the black hole attack and its variant pull off critical detriment to the entire network .In this type of attack, named black hole attack, the noxious node utilizes its routing principles, with the view to annunciate itself, that it has the briefest route to the target node. In this paper, we have investigated all the subsisting techniques and graded the solution with a table to understand their pros and cons.<strong></strong></p>

Wireless Adhoc Networks

The vehicle-Adhoc Networks are the specific type wireless adhoc networks, framed using the group of vehicles supporting the “on the fly’ communication between vehicles on the roadside. This is basically developed to handle the traffic in an intelligent manner avoiding the unnecessary time elapse, discomfort and the fatalities during the travelling and in turn improvise the convenience in the transportation providing a continuous traffic movement. But certain emergent situations such as the natural disasters, accidents, damaged roads, sudden break down of the vehicles and the appearance of the emergency vehicles disturb the regular traffic flow and safety of the on road vehicles. To ensure the safety of on road vehicles and elude the collision of the vehicles that take place due to improper communications or communication attacks, the paper puts forth an effective routing protocol with collision avoidance, (ERPCA) to identify vehicles with the reliability to transfer information on time and evade the discomforts in travelling. The evaluation of the ERPCA with the network simulator-2 evinces the improvement in the performance of the vehicular-adhoc networks
