Abstract:
This research paper presents a new relaying strategy for decentralized wireless networks that target mobile node motion recognition and prediction, using statistical reasoning to give portable devices more intelligence, which we term the Smart Relaying scheme. The aim of the proposed protocol is to enable intelligent terminals to observe the movement of adjacent wireless nodes so as to analyze the measured data and infer the targeted mobile subscriber motion strategies in different scenarios. This ability is of use within the Store-Carry and Forward Relaying scheme to create opportunities for the system to increase its overall performance. The motion data are processed by the Kalman Filter (KF) algorithm that can be seen as a series of prediction, tracking and smoothing calculations of the movement of mobile subscribers. The protocol is tested using the Opportunistic Network Environment (ONE) simulator. Compared with other DTN routing protocols in simple networks, the KF algorithm offers a well-controlled on hop count and overhead ratio with same delivery rate. In complex scenarios, the results show the KF routing protocol balances the delay, the times of relay and overhead ratio very well, which means the designed routing scheme delivers outstanding performance with good tolerance and resilience.
