An energy-efficient real-time routing protocol for sensor networks

Delay requirement becomes a key problem in sensor networks in the time-critical applications. This paper proposes an energy-efficient real-time routing protocol in sensor networks. A novel concept of Effective Transmission (ET) is put forward to ensure each forwarding node is farther from the source node and nearer to the destination node with respect to its sender. The end-to-end delay requirement is separated into the sum of point-to-point Constrained Equivalent Delay (CED). Each intermediate node can independently decide its next forwarding node according to each CED, so it will greatly simplify the route discovery process. The simulation results show the routing protocol is effective on the performance of energy consumption and end-to-end delay compared with some other routing protocols.

An energ-aware routing protocol based on effective transmission in sensor networks

In order to minimize the energy consumption in the discovery of the routing path, this paper introduces a novel concept of effective transmission (ET) that ensures each forwarding node is not only farther from the source node, but also nearer to the destination node with respect to its sender. An energy-aware routing protocol based on ET is proposed. It enables the energy consumption for each hop to be the least for the transmission. The simulation results show the routing protocol is effective in the performance of energy consumption comparing with some other routing protocols.
