The goal of this proposal is to extend the lifetime of wireless sensor networks by addressing the hotspot problem for a given application set. We propose to develop a collection of techniques, each addressing one particular aspect of the problem:o Ad-hoc routing techniques to distribute the traffic over the complete network rather than along a number of bottleneck traffic lanes.o Network topology management to equalize traffic density over the network.o Aggregation and distributed source-coding to compress the traffic flow in the vicinity of the monitor node.Algorithmic approaches to each of these problems are being proposed. Their impact will be quantified using a combination of analysis, simulation, and hardware prototyping on a smart building scenario.

该建议的目标是通过解决给定应用程序集的热点问题来延长无线传感器网络的生命周期。我们建议开发一个技术的集合，每个解决一个特定方面的问题：o Ad-hoc路由技术，以分布在整个网络，而不是沿着一些瓶颈交通通道的流量。o网络拓扑管理，以均衡网络上的流量密度。o聚合和分布式源编码，以压缩附近的监控节点的流量。它们的影响将通过分析、模拟和硬件原型在智能建筑场景中的组合来量化。
