Abstract |
|
|
| Node sleep scheduling is one of the most important methods to improve energy-constrained wireless sensor networks.
Most existing approaches to solve this problem require sensors’ location information, which may be impractical considering high
positioning costs. In this paper, an energy balanced non-uniform distribution node scheduling algorithm (EBNDNS) is proposed and
evaluated. This method needs distance between sensors instead of location information. A simple non-uniform distribution strategy
is also proposed. Combined with this strategy, simulation results show that EBNDNS can relieve the “energy-hole” problem for the
multi-hop communication and significantly prolong the lifetime of networks. |
