Neighborhood discovery and link management mechanism using hysteresis with an exponentially weighted moving average

Abstract

The neighborhood discovery and link management (NDLM) mechanism is an important component of routing protocols for self-organizing multihop wireless networks. High network performance is ensured when this mechanism quickly responds to topology changes and establishes stable links with an acceptable packet delivery ratio. The NDLM mechanism of optimized link state routing (OLSR) protocol is considered. This mechanism uses hysteresis with an exponentially weighted moving average. The efficiency of the mechanism is analytically estimated, and the mechanism is adjusted for various scenarios.
