Recently, wireless sensor in the video surveillance system plays an important role, but the sensor operation is limited by battery capacity. Obviously, the technique to reduce power consumption is necessary. In this paper, a novel lossless embedded compression (EC) algorithm is proposed to reduce the memory bandwidth in video coding. It comprises two core techniques of Multi-directional Gradient Detection...
Wireless ad-hoc sensor networks consist of small nodes with sensing, computing, and communicating capabilities. Energy deficiency is a key problem of these kinds of networks. Many routing, power management, and data dissemination protocols have been specifically designed for them where energy awareness is a chief design issue. This paper proposes a new probabilistic agent-based energy efficient routing...
Network lifetime is an important problem in sensor networks. The clustered method can enhance the efficient utilization of the limited energy resources of the deployed sensor nodes. In this paper, we describe the network lifetime as a function of the communication and data aggregation (DA) energy consumption and analyze the lifetimes of different transmission schemes in the homogeneous sensor networks...
