A reliable and energy-efficient MAC protocol for cluster-tree wireless sensor networks


This paper presents a reservation based enhancement of ZigBee beacon-only period approach, called R-BOP protocol, which addresses energy waste caused by not only idle listening but also overhearing and packet collision over cluster-tree wireless sensor networks. The protocol is based on traffic load estimation and a distributed medium reservation scheme to… (More)
