Investigating the performance of Key Based Broadcast Routing protocol

Wireless Sensor Networks (WSNs) are Mobile Ad Hoc Networks (MANETs) where the nodes are sensors usually with limited capabilities. These are often mobile, and are used to gather data about their environment and relay the date to a larger central node. They are often used in industrial applications or in dangerous areas. In this paper, the Key Based Broadcast Routing (KBBR) protocol is investigated. KBBR is a simple secure routing protocol designed for wireless sensor networks. KBBR aims to make efficient use of broadcasting by limiting the number of broadcast packets as well as providing security functions. The performance differentials are investigated using Network Simulator-2 (NS-2). Results demonstrate the merits of KBBR when compared with competing schemes.
