%0 Journal Article %T Power Efficient On-Data Collection Using Mobile Robot in WSN . %A Shiju Samuel %A S.Arulselvi %A Dr Kirankumar %J International Journal of Engineering Sciences & Research Technology %D 2013 %I %X The power efficient on data collection is to increase the energy efficiency condition even when there is problem in the failure of the main parent node. The on data collection is the concept, the power efficient data transfer in a network of nodes. The main concept that is used here is data gathering which is a method where the data from the child nodes are collected by the parent node first and then these child nodes sends the data to the base station periodically, if there exists a condition like failure of the parent node which collects the data, then the data will not be send to the base station. This paper propose a mobile robot which acts as a replacement for the failure and collects the data and forwards it to the base station. So that data loose is highly reduced. Thus the energy efficiency of the network is maintained. %K On-data Collection %K Mobile robot %K WSN. %U http://www.ijesrt.com/issues%20pdf%20file/Archives%202013/may-2013/20.pdf
