Efficient coverage and secured data transfer with load balance and connectivity preservation in wireless sensor networks

Providing complete coverage of sensing field as long as possible and maintaining the connectivity between the nodes is the main motto of the Wireless Sensor networks. The proposed system is implemented to provide maximum connectivity and extension in network-lifetime along with providing secured data transmission which is required for many applications. Maximum connected load balance cover tree algorithm (MCLCT) with Enhanced leach algorithm is used in the proposed system in this paper to gain full coverage as well as Base station connectivity of each sensing node by dynamically organizing load balancing routing cover trees. We are using Enhanced leach algorithm for cluster-head formation based on clustering-degree and residual energy and AODV (Ad hoc On-Demand Distance vector) algorithm for routing and for finding the shortest path form the source node to the BS using multi-hop technique. Enhanced leach and AODV are used in construction of dynamic maximum connected load balanced cover trees. To achieve more security and to reduce the energy consumption malicious node detection is done by using SET IBS scheme. Extensive simulation results shows that the proposed method outperforms all the results of existing methods in terms of energy consumption and network lifetime and connectivity.
