Wireless sensor networks are spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location. Multi-hop wireless networks use two or more wireless hops to convey information from a source to a destination. There is a loss of connectivity of nodes , the path creates partitioning of the network. To overcome this, cooperative transmission helps nodes to combine nodes to form a group and gains higher emission power as whole. So the final resulting power consumption is very less.So to avoid connectivity problems and to make the operation more effective we present cooperative transmission to connect previously disconnected parts of a network thus overcoming the separation problem of multi-hop network. This approach improves connectivity over 50% compared to multi-hop approaches and reduces the number of nodes necessary to provide full coverage of an area up to 30%.
