Abstract
From either practical or theoretical viewpoint, wireless sensor network (WSN) techniques are new and important research issues. Numbers of interesting applications for WSNs have been investigated, e.g., surveillance, target positioning, tracing, and health care. Sensor networks have been forecasted to apply variously, both the civilian and military domains.
There are two important issues usually are concerned on WSNs design. One is to construct a qualified WSN for applications to guarantee desired quality of service (QoS). The other challenge is to prolong the network lifetime. From application perspective, in order to improve the QoS supporting by WSNs, the ability of environment surveillance, target positioning, or target tracking have to be controlled carefully. Moreover, it is difficult to replace or recharge the battery for numerous sensors in the most scenarios. Hence, how to prolong the lifetime of WSNs also becomes a key challenge.
In this dissertation, we focus on the sensor deployment problem to support environment surveillance and target positioning services from various perspectives. Subsequently, we present each topic briefly as follows:
