Abstract:
WSNs is typically consist of a large number of senor nodes which collect and send various data to BS. WSN nodes are small battery powered devices having limited energy resources. Energy conservation is a major challenge because Wireless Sensor Networks are used in unattended locations. They have a restricted amounts of energy and are non-rechargeable batteries. Clustering enables in the efficient use and conservation of the limited energy resources accessible to distributed sensor nodes. Direct transmission in wireless sensor networks, where the cluster heads (CHs) and the base station (BS) are far from each other, is considered a critical factor because of its influence on network efficiency in terms of power consumption and lifetime. In multi-hop communication, the cluster head farthest away from the BS routes its data over several hops until they reach the BS. This thesis focuses on the discovery of an optimal path for an energy efficient intre cluster multi-hop communication between a source (CH) and a destination (BS) to reduce power consumption, which shall maximize network lifetimes, based on Centralized Energy Efficient Clustering Routing ( CEECR).As the simulation results reveal that in terms of normalized average energy consumption ,network life time and packet delivery ratio the proposed algorithm achieves relatively better performance than both Energy Efficient Multi Hop Routing using Genetic Algorithm (E2HMR-GA) and Multi-Hop Technique for the Improvement of LEACH Protocol (MHT) .The evaluation of the proposed method is conducted in MATLAB simulator and compared with other related methods. For instance, the simulation results of when compared to MHT, E2HMR-GA showed an average improvement of 4.1 percent, and 2.5 in packet delivery ratio, 5.5 percent, and 2.5 percent in normalized average energy consumption respectively.
