As one of the most challenging task of hybrid ad-hoc network is to provide Quality-of-Service (QoS) routing with multiple constraints, it is an NP-complete problem. Energy efficiency is an important design consideration in hybrid ad hoc network due to the limited battery life of mobile terminals. The network lifetime will be improved by suitably reducing the requirement of power for connections. In this paper, the authors propose a Energy Efficient Multi-constrained Link Stability based Protocol, EEMLSP. The proposed EEMLSP uses a new metric to find the route with higher transmission rate, less latency and better stability. It checks bandwidth, delay and jitter during route request and uses as well new mobility prediction mechanism in route reply to determine the stability of link during a path selection.
