【 摘 要 】

Secure Communication is important parameter in unattended and hostile environment. Wireless SensorNetworks (WSNs) are deployed and operate in vulnerabilities and are candidate networks which should becommissioned for security provisioning in end to end communications. Because of their specialized applicationsmany solutions in terms of cryptographic, Intrusion Detection and Key Management have been proposed. Mostsolutions lack and seem of ignoring the fact that route is as strong as weakest link in the route with respect toother links in the route. Variance of number of keys and high average number of keys on routes is an issue thatwe tried to resolve in our proposal using non-uniform key pre-distribution in Heterogeneous Wireless SensorNetworks (HWSNs). Analytical and Simulation based study supports our concern and reports an improvementin Average number of keys in almost 60 percent routes and decreasing variance in almost 50 percent routes inrandom and probabilistic neighbourhood.
