Investigating the Effect of Black Hole Attack on Zone Based Energy Efficient Routing Protocol for Mobile Sensor Networks

Mobile Sensor Networks (MSN) is a collection of mobilizer attached sensor nodes which can move randomly or task specifically. Routing is a basic step for data exchange in MSN. The routing protocols designed for ad hoc networks are suitable to MSN because they support mobility but due to resource constraint nature of MSN these protocols are not used directly. Hence we need new protocols. Zone based Energy Efficient Routing Protocol (ZEEP) is one of the new protocol in this direction which is the modified form of famous Ad Hoc On Demand Distance Vector Routing Protocol (AODV). The broadcasting nature of sensors presents a number of security threats to this kind of network. Black Hole Attack is one such deadly attack, which consumes data packets of the network and causes data loss. That badly affects the performance of the network. In this paper, we investigate this issue and proposed a new protocol known as Black Hole affected ZEEP or BZEEP. Our simulation results show that the effect of Black Hole Attack is less in case of BZEEP that proves ZEEP is more secure than traditional AODV in MSN area. For simulation purpose Network Simulator version 2.35 have been used. To support our views we used two quality of service parameters like Packet Delivery Ratio and Throughput and analyzed them using graphs that shows BZEEP gives high packet delivery ratio and throughput than Black Hole affected AODV or BAODV thus increasing the life time of the network.
