Energy preservation constitutes a very critical challenge in wireless sensor network surveillance applications. On one hand, transmitting data by using additional transmission power is among the biggest sources of energy consumption. On the other hand, using a small transmission power degrades the connectivity between nodes. In this paper, a Distributed transmission Power Control Method (DPCM) to minimize the consumed energy is proposed. Moreover, it aims to keep a good connectivity between nodes. These purposes are accomplished by adjusting, dynamically, the transmission power taking into account the connectivity information of the neighbors at one and two-hop. Simulation experiences are carried out to measure the performance improvements of the presented method in both static and mobile networks by using Castalia simulator. According to the obtained results, the authors' method minimizes the consumed energy without penalizing the connectivity between nodes compared to DPCS and farthest neighbor methods. In addition, DPCM achieves good performances in spite of node mobility.

The road surveillance based on wireless sensor network nowadays has received great attention and its application has been extensively used in practice. In this application, when the invasion target moves from road entrance to system protection points in road network, the nodes in wireless sensor network could detect the target timely and give an alarm before the target reaches the protection points.There are three main types of algorithms for nodes awake in road surveillance application presently, namely AAU(Always Awake-Up) algorithm, DC(Duty-Cycling) algorithm and Virtual Scanning Algorithm (VISA). VISA, which tailored and optimized for road network surveillance, has better performance than the others.This paper puts forward Virtual Scanning Algorithm based on Additional-area(VISAA), which introduces the more sleep time of the nodes based on the Additional Communication Area, to ensure the surveillance more reliability and effectively.The simulation results show that our algorithm has positive significance to improve the performance of road surveillance.
