Energy Aware Uniform Cluster-Head Distribution Technique for Hierarchal Wireless Sensor Networks

Summary Lifetime of a WSN is directly proportional to the energy consumption of its constituent nodes. In cluster-based routing, all the cluster-heads may be selected from one part of the network. Since routing in these networks are one of the major sources of energy drains, therefore Energy Aware Uniform Cluster-Head Distribution (EAUCD) technique which selects one node as a representative node from each part of the network is proposed. Looking at the simulation the proposed approach is better in terms of conservation of power. We also advocate grid deployment for cluster based techniques

Energy-aware and secure routing with trust levels for wireless ad hoc and sensor networks

This dissertation focuses on the development of routing algorithms for secure and trusted routing in wireless ad hoc and sensor network. The first paper presents the Trust Level Routing (TLR) protocol, an extension of the optimized energy-delay routing (OEDR) protocol, focusing on the integrity, reliability and survivability of the wireless network...The second paper analyzes both OLSR and TLR in terms of survivability and reliability to emphasize the improved performance of the network in terms of lifetime and proper delivery of data...The third paper proposes a statistical reputation model that uses the watchdog mechanism to observe the cooperation of the neighboring nodes...The last paper presents the results of the hardware implementation of Energy-Efficient Hybrid Key Management --Abstract, page iv
