INLyD: Inter-network-layer delay as a low-cost quality metric for multi-hop routing in wireless mobile networks
conference paper
The need for authentic and effective portrayal of the spatiotemporally changing quality of wireless links has gained wide attention especially over the last decade. Software-based link quality estimators (LQE) classify links with help of packet reception ratio (PRR), required number of packet transmissions (RNP) and scoring/grading schemes that again utilize PRR, RNP or retransmission based heuristics. On the contrary, this paper makes a case for inter-network-layer delay as a classification metric to boost end-To-end packet delivery in multi-hop communication. In essence our Inter-Network-Layer Delay metric (INLyD) uses a simplistic receiver-side in-band signaling scheme to passively accumulate queuing, retrying, back-off, transmission and propagation delay statistics while generating no additional control packet overhead. Our experiments show that the INLyD metric is not only light-weight (25% less MAC transmissions required per node) but substantially outperforms proactive broadcast based estimation schemes in static and mobile scenarios (1.7 and 1.2 times more end-To-end UDP delivery respectively for the performed experiments).
