• DESIGNING AND PERFORMANCE EVALUATION OF MODIFIED TDSR AND TDSR ROUTING PROTOCOL

Abstract

A dynamic local network i.e. MANETs is formed by a set of mobile wireless nodes. These networks do not have any central control infrastructure. This kind of network can be formed and integrated together. Also, they can be divided into separate networks without depending on any fixed infrastructure management. In this kind of network, each mobile node acts as a router instead of acting just as a host. These nodes also transmit and receive packets to and from other nodes. These features make MANETs to be more robust to security threats. Because the probability of eavesdropping, spoofing denial of service and impersonation attacks increases, MANETs need to be a trust model. So, trust management in MANETs has made variety applications such as security routing. In development of trust management system in MANETs, the highest focus is on developing secure routing protocols based on trust. In this work, we have presented two routing protocols TDSR (Trust based Dynamic Source Routing) and Modified TDSR. All the input parameters i.e.  Total number of nodes, Index of source node, Index of destination node, Node transmission range, Node X-coordinates and Node Y-coordinates and Nodes trust values are same for both of the methods as given in Table 1. Hop-by-hop method is used to find the route in TDSR method and Dijkstra algorithm is used in  TDSR method for the same. Also, output parameter i.e. trusted Path Distance, Trusted Path hops, Trusted Path Cost, Trusted Path and computational time are calculated to evaluate the performance of both methods. MATLAB R2013a has been used as an implementation platform.
