Impact of Sybil and Wormhole Attacks in Location Based Geographic Multicast Routing Protocol for Wireless Sensor Networks

Abstract

Problem statement: Wireless sensor networks have been used in many applications, such as home automation, military surveillances and entity tracking systems. The sensor nodes have low computational capabilities and are highly resource constrained. Routing protocols of wireless sensor networks are prone to various routing attacks, such as black hole, rushing, wormhole, Sybil and denial of service attacks. Approach: The objective of this study was to examine the effects of wormhole in conjunction with Sybil attack on a location based-Geographic Multicast Routing (GMR) protocol. Results: The NS-2 based simulation was used in analyzing the wormhole in conjunction with Sybil attack on GMR. Conclusion: It is found that, the Sybil attack degrades the network performance by 24% and the wormhole attack by 20%.
