In contrast to generic sleep/wake scheduling schemes, our proposed algorithm performs scheduling that is dependent on traffic loads. Nodes adapt their sleep/wake schedule based on traffic loads in response to three important factors, (a) the distance of the node from the sink node, (b) the importance of the node's location from connectivity's perspective, and (c) if the node is in the proximity where an event occurs. Using these heuristics, the proposed scheme reduces end-to-end delay and maximizes the throughput by minimizing the congestion at nodes having heavy traffic load. Simulations are carried out to evaluate the performance of the proposed protocol, by comparing its performance with S-MAC and Anycast protocols. Simulation results demonstrate that the proposed protocol has significantly reduced the end-to-end delay, as well as has improved the other QoS parameters, like average energy per packet, average delay, packet loss ratio, throughput, and coverage lifetime. © 2011, Nazir et al; licensee Springer. date: 2011 publisher: Springer International Publishing official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84964194335&doi=10.1186%2f1687-1499-2011-92&partnerID=40&md5=0bf62a49cea14b47a99055f6e7194c43 id_number: 10.1186/1687-1499-2011-92 full_text_status: none publication: Eurasip Journal on Wireless Communications and Networking volume: 2011 number: 1 refereed: TRUE issn: 16871472 citation: Nazir, B. and Hasbullah, H. and Madani, S.A.
