Analysis and Countermeasures of Wormhole and Sinkhole Attacks in WBAN

Wireless Body Area Network (WBAN) is a promising technology that having significant number of applications in healthcare. Despite several benefits, WBAN susceptible to security attacks, particularly related the node misbehavior attacks such as sinkhole, wormhole, blackhole, and grayhole attacks. In this research work, performance AODV protocol against wormhole sinkhole has been analyzed. This comparison-based study achieved for PDR (Packet Delivery Ratio), NRL (Normalized Routing Load), residual energy, packet loss, average throughput, end-to-end delay metrics with 20 50 nodes respectively. The results show network throughput 32% 53% more than attack, However, 36% e2e 63% less attack. network, attack 26% 10.7% Though, delays are 41.7% 78.5% Hence, either destructive Based on simulation results, some solutions mentioned have recommended.
