L‟auto organisation en cas des pannes dans les réseaux de capteurs sans fil hétérogène (Protocole ADAPTRP-AO)

Abstract

In these last years WE have Seen the emergence of multi-hop wireless network Thanks to its unique capabilities, different characteristics and various target applications, we can define RCSF wireless sensor networks These last years are self-organized networks and they made up of a large number of autonomous sensor nodes with low resourcrs (computing capacity, memory, transmission power etc …) In this context we studied the self-organization in case of failures in wireless heterogeneous sensor networks. Initially: we were interested in self-organization in a heterogeneous context based on the Idea that resources in operator nodes must be exploited to reduce the communication load in the sensor nodes. Finally: we present a routing ADAPTRP-AO(ADAPTRP-auto-organized a hybrid routing protocol which IS an extension of the ADEPTRP protocol the solution is effective for self-organization at the level of ordinary nodes the heads of the block and the base station it's suitable for application requiring reliability and fault tolerance as it ensures that all IS properly transfered to the base station in spite of the presence of different types of damages because of energy hard ware failure mistakes and communication.
