Routing and power adaptation for mostly-on wireless sensor networks applications

Wireless sensor networks (WSNs) have received much attention in the last few years especially with regard to routing protocols and transmission power adaptation. The main goal of power adaptation is to improve the performance and the lifetime of WSNs. By selecting the suitable Transmission Power Level (TPL), the battery lifetime of sensor nodes is increased and better overall network performance is achieved. In this paper, we investigate the impact problem of TPLs coupled with static routing in mostly-on many-to-one WSN applications. In such network pattern, all sensor nodes generate and continuously send data to a single sink via single-hop or multi-hop transmissions. The impact of routing coupled to TPLs is evaluated using network metrics such as: Packet Delivery Ratio (PDR), energy consumption, transmission latency.
