Energy Efficiency in OLSR Protocol

In this paper we study in details the optimized link state routing (OLSR) protocol for ad hoc networks. In particular, we investigate its performance by focusing the attention on its energy efficiency. To have some terms of comparison the performance are compared with those of other routing schemes. Furthermore, to improve the energy efficiency by increasing the network life time, we propose and discuss a power controlled version of OLSR. OLSR power controlled provides the optimal paths in terms of minimum power needed to reach the destination, and not in terms of number of hops as in the classic version. By means of extensive simulations, we show that, in many system conditions, OLSR power controlled is able to achieve good energy savings
