Analysis of Existing Trust Based Routing Schemes Used in Wireless Network

Abstract

Wireless networks are vulnerable to many security attacks as they use wireless media and a node has to depend on unknown intermediate nodes for data transmission. Cryptographic algorithms used for wired network cannot work efficiently in wireless network, as in wireless network nodes are mobile and battery operated. Nodes may also have limited resources available. So, to detect malicious activities on node and improve stability of route while routing in mobile ad hoc network, trust-based routing is used. Communication parameters used in calculating trust value in most of existing trust based protocol (wireless network) are number of successful session or packet forwarded between two nodes, number of packet dropped or delayed, response time, battery life, mobility of node etc. This paper provides analysis of existing trust based routing by surveying current “sate of the art” work in this area. This paper also proposed a new parameter (number of route error message sent by a node) of a wireless node which can affect the network performance and can be used to calculate trust value.
