Localization is a fundamental operation in inobile and seIf-corlfguring iienuorks such as sensor networks and mobile ad hoc riemorks. For example, sensor location is ofen critical for data interpretation. Existing research focuses on localization mechaizisms: algorithms and infrastructure designed to allow the sensors to detemtine their location. In a mobile em&-oiinzerir, the underlying localization nzeclmnisni niust be invoked repeatedly to rlzaintain accirrate location irlfor7nation. We propose and investigate ndaptive and predictive protocols that corztrol the frequency of localization based on sensor mobility behavior to reduce the energy requireinerits for localization while bounding the localization error In addition, we evaluaie the energy-accuracy rradeoffs. Orrr results indicate that the proposed protocols reduce the localization energy significantly without sacrijcirzg acairacy.
Tilak et al. REF study the time interval for broadcasting of the mobile beacon and propose an adaptive and predictive protocols that control the frequency of localization based on sensor mobility behavior.
