dc.description.abstractPEGASIS, a hierarchical chain based protocol, is an important protocol architecture for routing in WSNs. Till now many protocols based on PEGASIS have been proposed to improve the Lifetime of network and its load balancing capabilities. IEEPB was proposed to remove certain limitations of EEPB such as problem of Long Link, non-optimal selection of leader node and huge time delay involved in data transmission. Similar to EEPB, IEEPB allowed branching in chain which produces nodes with different degrees which imbalances the energy consumption due to data fusion at each node and leader selection still remains less optimal as it does not consider the difference in degree of nodes and leads to the early death of sensor nodes. This results in poor load balancing in the network. In our work, we propose a method to solve this load balancing problem in more efficient way by considering node degree threshold and distance between nodes while building chain and node degree, initial energy, residual energy and distance as key parameters in leader selection. Also, a new method is adopted for data transmission to reduce time delay. Similarly, M-PEGASIS was also proposed as an improvement over PEGASIS. This uses a new method for formation of chain as well as leader selection but the mechanism of data transmission remains same as PEGASIS. It still suffers with the problem of Long Links, non-optimal chain formation, low load balancing among nodes and huge time delay. In our work, we also propose another method to solve the said problems in more efficient way by introducing a chain reconstruction phase and by adopting new mechanism to gather and transmit data. Simulation performed using MATLAB R2010a shows that the Proposed1 and Proposed2 protocols have better energy efficiency and load balanced energy consumption with reduced time delay as compared with IEEPB, PEGASIS and M-PEGASIS respectively.en_US
