An energy-aware topology control in wireless sensor network

nr katalogowy: 69622

Wireless sensor networks have become an emerging technology that has an incredibly wide range of prospective. Typically, a network consists of a large number of nodes, distributed over some specific area and organized into multi hop system. The node of wireless sensor network is simple device equipped with control unit, communication unit, sensing unit and power supply. The power supply is usually a small, low capacity battery which is very hard to replace. It makes the energy factor of the sensor node a crucial one. This fact imply that the power supply of a node should be managed very carefully, to achieve longer life of the node. In the opposite to the energy conservation are often the objectives, which the network has to fulfill. Energy efficient topology control means to allow the network conserves the energy and keep the network performance on acceptable level. The topology control can be broadly categorized into any of the two approaches. First is called the nodes activity control. The basic idea of this group of methods is to maintain a small subgroup of nodes operative, while the rest of nodes go into sleep mode. The other methods are called sleep/wakeup algorithms. The nodes with implemented sleep/wake-up algorithm stay active for a small period of time and then turn into sleep mode, where the communication, sensing and control units are deactivated. Related work Much of the related research are addressed to WSN that are dense, battery powered and self configured. Because of these requirements, most of the author are concentrated on finding solution at various levels of the communication protocol, including extremely energy efficient aspects [1]. Some of the most popular solutions in energy effective topology control are GAF, SPAN, ASCENT, STEAM, SWP. Comparing the methods described above, GAF and SPAN can reduce the energy consumption 3 times [2], ASCENT more than 5 times [2]. In group of sleep/wakeup methods, the[...]
