Optimal, Secure Cluster Head Placement Through Source Coding Techniques in Wireless Sensor Networks

摘要

In many applications of wireless sensor networks (such as military communications), secure communication, message delay minimization and energy efficiency are crucial. Such requirements constrain special or Important Cluster Head (ICH) placement over the network architecture modeled by a tree. The optimal important cluster head placement problem is formulated and solved using source coding results (providing minimum possible delay and security through prefix-free paths over the tree). Also, through simulations energy efficiency of the proposed approach is established. The reported research is naturally applicable for many applications of Wireless Sensor Networks (WSNs) such as Body Area Networks (BANs).
