In Wireless Multi-hop Networks (WMhNs), routing protocols with energy efficient and delay reduction techniques are needed to fulfill users' demands. In this paper, the authors present Linear Programming models (LP models) to assess and enhance reactive routing protocols. To practically examine constraints of respective LP models over reactive protocols, they select AODV, DSR and DYMO. It is deduced from analytical simulations of LP models in MATLAB that quick route repair reduces routing latency and optimizations of retransmission attempts results efficient energy utilization. To provide quick repair, they enhance AODV and DSR. To practically examine the efficiency of enhanced protocols in different scenarios of WMhNs, they conduct simulations using NS- 2.
