  In Wireless Ad-hoc Networks, nodes are free to move randomly and organize
themselves arbitrarily, thus topology may change quickly and capriciously. In
Mobile Ad-hoc NETworks, specially Wireless Multi-hop Networks provide users
with facility of quick communication. In Wireless Multi-hop Networks, routing
protocols with energy efficient and delay reduction techniques are needed to
fulfill users demands. In this paper, we present Linear Programming models to
assess and enhance reactive routing protocols. To practically examine
constraints of respective Linear Programming models over reactive protocols, we
select AODV, DSR and DYMO. It is deduced from analytical simulations of Linear
Programming models in MATLAB that quick route repair reduces routing latency
and optimizations of retransmission attempts results efficient energy
utilization. To provide quick repair, we enhance AODV and DSR. To practically
examine the efficiency of enhanced protocols in different scenarios of Wireless
Multi-hop Networks, we conduct simulations using NS-2. From simulation results,
enhanced DSR and AODV achieve efficient output by optimizing routing latencies
and routing load in terms of retransmission attempts.
