Wireless mobile adhoc network (MANET) is a dynamic network. Nodes in a MANET have high degree of mobility from one domain to another in a particular time interval. In such a dynamic network, security is a major concern. In this paper, the authors propose an inter domain agent based secure authorization and communication for mobile clients/nodes (MCs) in MANET. Mobile agents (MAs) are software programs that support the mobility of clients in different domain and provide necessary resources to the clients for safe execution. It also shares the key with MCs in different domains. An algorithm for secure authorization and communication between MCs having mobility in different domains is proposed. The scheme is evaluated on ns-2 w.r.t. metrics such as overall cost in terms of overhead generated, admission and traceability cost, and itinerary chosen by MAs w.r.t. mobility of MCs.

Crossover And Mutation

The paper proposed a novel methods in order to solve the congestion and routing oscillation, which based on crossover and mutation of the ant colony algorithm to achieve dynamic QoS routing realization. The algorithm expanded the scope of the search path selection adaptively adjust the strategy and the amount of information to determine the probability of renewal strategy, which can better adapt to dynamic network environment, you can make the shortest possible path of choice to meet the real-time applications, while avoiding link load is heavy, maintaining the distribution of network load balance. The simulation results show that the routing algorithm has better convergence speed and stability, which can more effectively address congestion and routing oscillation, its performance compared with traditional methods have been noticeably elevated, indicating it has a better multimedia network environment flexibility.

The research of using wireless sensor network to settle the problem of urban traffic has become a hotspot in the fields of intelligent transportation system. In this paper, a wireless sensor network model based on mobile agents is proposed. Since mobile agents have characteristics of autonomous collaboration and asynchronous interaction, this model owns the abilities of adapting to the dynamic network changes, reducing the network load and enhancing the data fusion. In the application of the model, the travelers can be guided to choose the right road line through calculation of the predicated value of traffic congestion, so the condition of the traffic congestion can be remitted in some way.
