Optimising on trust value-based clustering using trust evaluation scheme for ad hoc network

Abstract

In ad hoc networks, routing and security are a very challenging task due to their peculiar characteristics. Among various routing schemes and providing security for optimising on trust value-based clustering using trust evaluation scheme CTES for ad hoc network is based on an efficient trust model. This algorithm aims to elect trustworthy cluster heads that can provide secure communication via cooperative nodes and is used to settle down many secured applications in ad hoc networks. Thus, the trust level of a node must be dynamically taken into consideration in the parameter used for cluster head election. Furthermore, nodes energy, mobility, distance to neighbours and connectivity degree are also used for cluster heads election to make CTES result in a trustworthy, stable and high-energy cluster heads. Simulations were conducted to evaluate trusted cluster heads in terms of cluster stability, packet delivery ratio and an average end to end delivery.
