Wireless Sensor Networks (WSNs) are gaining much importance due to their varied characteristics and the ease with which they can be implemented in various environments to suit different purposes. The sensor nodes which are the main components of WSNs are typically battery equipped and difficult to recharge. Hence, the primary concern while designing such networks is to reduce the overall power consumption...
Machine-to-machine (M2M) communications have emerged as a cutting edge technology for next-generation communications, and are undergoing rapid development and inspiring numerous applications. This article presents an investigation of the application of M2M communications in the smart grid. First, an overview of M2M communications is given. The enabling technologies and open research issues of M2M...
This paper presents an infrastructure sensor network and an adaptive MAC. The sensor network is intended for low power wireless sensor monitoring network which could tolerate certain amount of packet loss. Trade-off between power consumption and packet loss rate which application could tolerate is made. An adaptive MAC, which will choose Just-Send mechanism or classic pure ALOHA technique according...
A cluster-based routing scheme for wireless sensor networks featuring adjustable cluster size is proposed in this article. Aimed at the reduction of power consumption, the proposed scheme is designed to adjust cluster sizes on the fly such that communication loads can be evenly shared by individual nodes, and consequently extend the lifetime of an entire sensor network. In the proposed scheme, named...
Through analysis of energy consumption of wireless sensor networks with uniform node distribution, this paper finds that energy hole in the wireless sensor networks with uniform node distribution can not be avoided. When network lifetime ends, as much as 90% of network energy remains. However, network lifetime can increase several times by selecting different transmission power levels. The main conclusions...
The multi-scenario of the topology in the hybrid ad hoc networks is studied and a novel cross layer resource scheduling scheme based on the topology is proposed in this paper. The proposed scheme integrated the attributes both of the new performance evaluation machine link resource check metric (MLRCM) and the topology space with the special multi-scenario. The power consumption of each node can be...
