    Mobility Impact on Mobile Ad hoc Routing Protocols
    (IEEE Computer Society, 2003) Djenouri, Djamel; Derhab, Abdelouahid; Badache, Nadjib
    An ad hoc network is a set of mobile units connected by wireless technologies, making an infrastructureless temporary network. without turning to a central administration. The network topology is unpredictable, dynamic, it may change any time. These topology changes make ad hoc networks challenging to implement routing protocols. In this paper, we study mobility effects on the performance of several mobile ad hoc routing protocols.

    An Energy Efficient routing protocol for mobile ad hoc networks
    (IFIP, 2003-06) Djenouri, Djamel; Badache, Nadjib
    power consumed for routing data-packets in wireless ad hoc networks can be significantly reduced compared with the current min-hop max-power routing protocols. One of promising mechanisms proposed to reduce energy consumption is power control. Doshi & Timothy [7] have presented an implementation of this mechanism, and defined a new minimum energy routing scheme. We think that the aim of an efficient routing protocol is not only to minimize energy consumption to route packets, but also to ensure a long life to all nodes. In order to avoid the network partition as long as possible. In this paper, we define new metrics to resolve the tradeoff between: minimising energy consumption to route packets, on the one hand, and ensuring a long life to all nodes’ batteries, on the other hand. We also define a new technique which allows the distribution of the routing task over nodes then we modify DSR protocol, to improve it and to make a new power-aware and power efficient protocol.
