In this section, we present the details of proposed protocol. Our protocol implements the idea of probabilities for cluster heads selection based on initial energy and residual energy of sensor nodes as well as the average energy of the sensor network. Proposed algorithm consider three types of nodes every type have different initial energy level. normal nodes have E_0 energy. m advanced nodes have a times energy more than normal nodes with E_0 (1+a) energy level. m_0 super nodes have b times energy more than normal nodes with E_0 (1+b) energy level, where a and b are energy factors. As N is the number of total nodes in network, then for number of normal nodes, advanced nodes and super nodes N(1-m) , Nm〖(1-m〗_0) and Nmm_0 in the network, respectively. The …show more content…

Therefore, a protocol treat heterogeneity more important than homogenous protocol. Our proposed algorithm implements the same method for estimating the energy in the network as in DEEC [-----]. Since the probabilities calculated depend on the average energy at round r in the network. This average energy estimated as: E ̅(r)=1/N E_total (1-r/R) Total rounds for network life time calculated as: R=E_total/E_round Where E_round energy dissipated during a single round in a network and calculated as: E_round=L(2NE_elec+NE_DA+kE_amp d_(to BS)^4+NE_fs d_(to CH)^2) (1) Where k is number of clusters, d_(to BS) average distance between CH and BS, d_(to CH) is average distance between cluster head and cluster member. Now, d_(to CH)=M/√2πk , d_(to BS)=0.765M/2
