Abstract
Advancement in wireless sensor network (WSN) technology and sensor instrumentation has
contributed to the development of novel protocols which are designed specifically for WSN,
where conservation of energy is of utmost importance. Though, the performance of the clusterbased
routing protocols is limited by problems related to determining an accurate and energyefficient
radio model for the sensor nodes in the network. A number of radio models have been
proposed to improve the performance of WSN clustering routing protocols but the basic
assumptions and inaccurate configuration of these radio models make them ineffective and most
time lead to poor utilization of the limited energy and computational resources. This paper
addresses this challenge by proposing an improved radio model that incorporates specialized
data transmission schemes, stepwise energy level and capable of adapting to frequent changes in
the position of the motes without hindering the reliability of the data transmission to the sink,
despite fluctuations due to signal interference. The proposed radio model was incorporated into
the Low-Energy Adaptive Clustering Hierarchy (LEACH) protocol and called LEACH-IMP. The
proposed LEACH-IMP shows a better performance in terms of the energy consumption, number
of packets received, signal interference and network lifetime when compared to LEACH routing
protocol.
