Title
Look-ahead scheduling for energy-efficiency and low-latency in wireless sensor networks
Abstract
The operation of a sensor node is limited by the initially equipped battery which is hard to be recharged or replaced. Thus reducing unnecessary energy consumption is one of the most important requirements. Most energy waste is from the always-on wireless interface and many new MAC protocols have been suggested to solve the problem. However, they sacrifice the MAC latency, especially, with multi-hop forwarding.In our approach, we designed a novel MAC protocol which has both low latency and power efficiency by separating channel reservation process and data transmission process. The sensor nodes having data to forward are efficiently scheduled during reservation process. The other nodes with no schedule go to sleep to save energy and only scheduled nodes are awake during scheduled time and transmit data. The performance of our protocol is evaluated through simulations.
