Wireless Networks have been part of our daily life in the last decade or so.The advances in wireless networks helped it to sustain, enrich and adapt to multiple applications which a human interacts.In last decade, researchers have specifically shown lots of interest in the area of mobile ad-hoc and sensor networks.This paper proposes a practical solution for spatial reuse routing in wireless sensor networks.There has been many research papers that address the concept of spatial reuse, but very few discuss the spatial reuse for routing.The disadvantage with most of these research works is that the complexity of finding the spatially reusable links.In this paper, we propose a conservative approach for spatial reuse which reduces the complexity of finding spatially reusable links.This approach is called conservative because we carefully choose the spatially reusable links in the routing path and sometimes this choice may not be optimal.However, the overhead that we incur is because of the reduction in the complexity of finding spatially reusable links in the routing path.The experimental results show that the conservative spatial reuse routing performs comparable to that of spatial reuse routing with the reduction in the complexity of finding the routing path.We validate our claims through both analysis and simulations.
