Abstract : Wireless sensor networks are comprised of independent sensors used to monitor physical/environmental conditions for example temperature, humidity and are distributed spatially. These sensors transmit their collected data to a sink. These sensor nodes are often put in distant areas where a constant energy supply can be a major challenge. Hence the sensors are generally battery operated which limits their energy consumption. An energy efficient optimization algorithm can prevent nodes from being profligate consumers of battery power and use it judiciously instead. Hierarchical routing protocols are the best known protocols to optimize energy consumption in WSNs. ILEACH is considered one of the best among them. To optimize the lifetime, it selects sensor nodes with higher residual energy and lower distance from the Base Station (BS) as Cluster Head (CH) nodes. Then it intelligently manages these nodes by constructing clusters such that the lifetime of WSN is maximized and its average energy dissipation is minimized. TDMA protocol is used for intra cluster communication. This paper proposes a modification of ILEACH protocol by introducing intercluster communication where cluster heads are arranged in a hierarchy, further optimizing the WSN lifetime. Keywords— Wireless Sensor Networks, Optimising ILEACH, Heuristic Multihop Algorithm, Static Wireless Nodes.
