Greedy routing protocols provide a scalable and cost effective solution for routing packets in mobile ad-hoc networks (MANETs). However, such routing protocols can not be used in the networks where holes exist. We propose a virtual ring-based hole avoiding routing protocol (VRHAR) in MANETs where holes exist. Simulation studies show that the proposed(More)
We design Piecewise QoS Routing (PQR) protocol in large-scale Mobile Ad-hoc NETworks (MANETs) considering bandwidth and delay constraints. We use super nodes to periodically maintain k-hops neighborhood information. The proposed protocol can quickly find a local routing path from a super node to its next super node which satisfies QoS requirements. A whole(More)
