Interface Activation in Multi Radio Wireless Networks

Abstract

Wireless sensor network is used in a wide range of applications, and the technological advancements have allowed of having more than one radio in a sensor node. Wireless radio networks have wide range of functionality which can be used in places to get data and send to a monitoring base station constantly in certain intervals of time or when needed where manned work might seem hard. There are many issues to be considered in a wireless sensor network of which power consumption is one of the major issues. It is important for a sensor node to stay active for longer time in order to have the network connected. The nodes cannot be recharged every time, where energy has to be used more efficiently in every sensor nodes. Our goal is to minimize the total energy consumption and energy consumption along the path from the node to the base in a wireless multi-radio network and also reduce the latency for each sensor node to send data to the Base station, which means the data, can be sent to the base as quickly as possible without any delay. The problem has been defined for N radios in each sensor node and a sensor network with two radios has been considered for describing the problem and differentiating it from the existing algorithms. A plausible solution to the problem has also been proposed and implemented and their results compared with existing algorithms.
