Ad hoc networks have being given a lot of attention in recent years. The problems associated with this kind of networks are many and difficult to solve because of their dynamic nature – networks with non-static topology and non-static infrastructure. A large number of the issues under investigation are related with the finite power of the mobile devices. In terms of the communication tasks that those devices perform, the transmission power that is utilized plays a very important role to the long-term survivability of the network. The issue of transmission power affects the connectivity of the network, in a way that when the utilized transmission power is small then the network may be partitioned. In this work the latter has equivalent importance with the case where the assignment of excessive transmission power, resulting in a very dense net of communication links. When we use large transmission power then the long-term survivability and connectivity of the network is jeopardized because the nodes use their finite power inefficiently. Our task is to adjust the transmission power to the level where both the connectivity of the network is ensured and the transmitted power is minimized among all participating devices.
