Adapting Dynamically Neighbourhood Table Entry Lifetime in Wireless Sensor Networks
Neighbour discovery and maintenance of neighbourhood tables have importance in wireless sensor networks. Almost every upper layer application such as routing or self-organizing relies on neighbourhood tables. Imprecise tables may lead to failures that may be costly in terms of resources which are very limited in such networks. Neighbourhood tables are achieved thanks to the Hello protocol. Several studies propose smart schemes to dynamically adapt the frequency of Hello messages but none of them investigates the way the refreshment period of entries in table should be adapted.
