Enhanced Distributed Energy Efficient Clustering Protocol

Today WSN are highly approached technology that used to interact several sensor nodes corresponding to at least common application. The WSN is affected by the problem of energy dissipation of the sensor node that collects and report the specific data to application monitoring node. The main reason to develop WSN network is to maximize the lifetime of the batteries that are constrained by the nodes during transmission. The clustering mechanism is the best and most efficient one to resolve the issue with the requirement of energy in WSN. In clustering the network is divided into smaller clusters and each cluster includes one cluster head and members. It is very much useful for reducing the energy dissipation and enhancing the lifetime of the network. In this paper we propose new clustering protocol Enhanced DEEC (distributed Energy Efficient Clustering) along with priority queue to balance the energy in the WSN network and prolonging the lifetime of the network. The simulation results revealed the performance of the proposed technique is better than existing protocol DEEC. Result improvement of 20% is observed through the proposed mechanism. Proposed system uses DEEC along with priority queue to save from packet drop. The dropped packet first of all stirred within the priority queue from where it is fetched and given to next cluster head having sufficient energy for transmission. In addition distance between the nodes and cluster head is also considered to reduce the energy consumption during transmission of packets. Energy consumed during overall packet transmission, packet drop ratio, number of packets transmitted to the base station and cluster head are considered parameters. In addition nodes becoming dead at various intervals or rounds are also obtained through the proposed simulation.
