Secured Cluster-Based Routing Protocol

Ad hoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. In the recent past, most of the ad hoc network routing protocols are cooperative in nature and rely on trust-your-neighbor relationship to route packets among participating nodes. This native trust may paralyze the network with an attack of minimum effort. The dynamics of the ad hoc routing protocols have been studied but security issues and concerns have not been paid much attention. This paper proposes a cluster-based routing protocol with the incorporation of some security in simple manner. Hereafter, the proposed protocol is referred to as Secured Cluster-Based Routing Protocol (SCBRP). This protocol can easily identify and prevent malicious attacks during transmission. With a suitable simulation setup, the protocol has been simulated with 150 nodes and the simulation results have been compared with other cluster-based routing protocols, such as PCBRP-opt and Blind Flooding (BF). The obtained results are in good agreement with those of others. It can be stated that the scheme is robust, secure and provides accurate routing information in a timely manner
