In energy constrained wireless sensor networks, energy conservation techniques are to be applied in order to maximize the system lifetime. We tackle the problem of increasing netw...
We introduce iPoint, a passive device that can interact and deliver information to virtually any mobile phone equipped with a WiFi network interface and a camera. The iPoint does n...
There has been a lot of work on localization for sensor networks. Most localization schemes assume an already deployed network. Very little research has been done for active senso...
Clustering and aggregation inherently increase wireless sensor network (WSN) lifetime by collecting information within a cluster at a cluster head, reducing the amount of data thr...
Security protocols are not as secure as we assumed. In this paper, we identified a practical way to launch DoS attacks on security protocols by triggering exceptions. Through exp...
