SQ-AODV: A Novel Energy-Aware Stability-Based Routing Protocol for Enhanced QoS in Wireless Ad-Hoc Networks
The authors propose a novel, energy-aware, routing protocol for Quality-of-Service (QoS) support in an infrastructure-less ad-hoc network. Their Stability-based, QoS-capable Ad-hoc On-demand Distance Vector (SQ-AODV) protocol is an enhancement of the well-known Ad-hoc On-demand Distance Vector (AODV) protocol. Their protocol utilizes a cross-layer approach, in which information about residual node energy is used for route selection and maintenance, and for quickly adapting to network conditions. The uniqueness of their scheme is that it uses only local information, requires no additional communication or co-operation between nodes, possesses a make-before-break capability that minimizes packet drops, and is compatible with the basic AODV data formats and operation, making it easy to adopt.
