'AN IMPROVED WIRELESS TRANSCEIVER DEVICE WITH REDUCED CONTROL PACKET OVERHEAD IN MOBILE AD HOC NETWORKS'

摘要

The present invention relates to a localized and distributed mechanism for improving the efficiency of transceiver and reducing control packet overhead in a Mobile Ad hoc Network (MANET). Each mobile, portable network device includes at least one wireless transceiver, a processor, GPS device and control system. The processor, GPS device and control system are logically coupled to the wireless transceiver to facilitate digital communication and to know the speed of network device. Every transceiver which is integrated with each mobile node forwards Route Request packets (RREQs) with an adjusted probability (P) value of which is based on speed (S) of that particular node and number of neighbours (N) to that node. The system uses hello mechanism (to find number of neighbors N) and position system (Global Position System) device (to find speed of node S) as a decision criteria to evaluate the value of adjusted probability P. This improved transceiver device is very useful in networks where mobile devices are used and dynamic topologies are formed.
