摘要：Completely GPS-free positioning systems for wireless, mobile, ad-hoc networks typically stress on building a network-wide coordinate system. Such systems suffer from lack of mobility and high computational overhead. On the other hand, specialized hardware in GPS-enabled nodes tends to increase the solution cost. A number of GPS free position based routing algorithms have been studied by the authors before proposing a new positioning framework in this paper. The proposed positioning framework is characterized by using only a handful of GPS enabled nodes. Lower dependence on specialized GPS hardware reduces the total cost of implementing the framework. A new location aided routing protocol called Location Aided Cluster Based Energy-efficient Routing (LACBER) has been proposed in the paper. Simulation results show that using the proposed positioning framework, LACBER turns out to be efficient in lowering mean hop and hence in utilizing the limited energy of mobile nodes.
