ABSTRACT
This research work proposes a mathematical model for the lifetime of wireless sensor networks (WSN). It also proposes an energy efficient routing algorithm for WSN called hierarchical energy tree based routing algorithm (HETRA) based on hierarchical energy tree constructed using the available energy in each node. The energy efficiency is further augmented by reducing the packet drops using exponential congestion control algorithm (TCP/EXP). The algorithms are evaluated in WSNs interconnected to fixed network with seven distribution patterns, simulated in ns2 and compared with the existing algorithms based on the parameters such as number of data packets, throughput, network lifetime, and data packets average network lifetime product. Evaluation and simulation results show that the combination of HETRA and TCP/EXP maximizes longer network lifetime in all the patterns. The lifetime of the network with HETRA algorithm has increased approximately 3.2 times that of the network implemented with AODV.

Mentions: Simulation experiments are conducted in ns 2 using the seven node distribution patterns (see Box 1). Coverage of a sensor node is evaluated by conducting a simulation experiment with only two wireless nodes. In this simulation experiment the height of the antenna and the transmission power are varied to find the minimum height required and the optimum power for covering a diagonal distance of 80 m is found for each pattern. By using various parameters like channel type, propagation mode, network interface type, mac type, interface queue type, antenna, interface queue length, routing protocol, and antenna height the wireless sensor network interconnected with fixed TCP/IP network is simulated with the seven node distribution patterns discussed earlier in this section.
