We propose a distributed on-demand power-management protocol for collecting data in sensor networks. The protocol aims to reduce power consumption while supporting fluctuating dem...
In most of the ad-hoc routing protocols, a static link lifetime (LL) is used for a newly discovered neighbors. Though this works well for networks with fixed infrastructures, it is...
We study a novel "coverage by directional sensors" problem with tunable orientations on a set of discrete targets. We propose a Maximum Coverage with Minimum Sensors (MCM...
— A significant amount of research effort is being carried out by the research community to increase the scope and usefulness of wireless sensor networks; to optimise life time ...
— We consider the problem of aggregating data at a mobile fusion center (fusor) (eg. a PDA or a cellular phone) moving within a spatial region over which a wireless sensor networ...
