Energy-Efficient and Reliable Medium Access in Sensor Networks
Vivek Jain, Ratnabali Biswas, Dharma Prakash Agrawal · 2007
Energy efficiency and reliable data delivery are the two most important parameters for designing wireless sensor network protocols. Wireless communication is inherently unpredictable and error-prone. Hence, reliability is required to ensure that a packet reaches its desired destination; otherwise the energy expended in forwarding the packet is wasted On the other hand, energy-saving mechanisms are required for battery-constrained sensor networks. In this paper, we have designed an on-demand energy-efficient and reliable medium access control (E2RM: AC) protocol that enables reliable data delivery and energy conservation without affecting packet latency. We have demonstrated the superior performance of E2RMAC over existing energy-efficient and reliability-enforcing approaches in terms of reliability, latency, scalability and energy-efficiency.
