—We consider a wireless cognitive radio network in which a set of secondary users (SUs) opportunistically utilize the wireless spectrum licensed to the primary users (PUs) to tra...
Error resilient encoding in video communication is becoming increasingly important due to data transmission over unreliable channels. In this paper, we propose a new power-aware e...

In a wireless sensor network of N nodes transmitting data to a single base station, possibly over multiple hops, what distributed mechanisms should be implemented in order to dyna...
Current algorithms for minimum-energy routing in wireless networks typically select minimum-cost multi-hop paths. In scenarios where the transmission power is fixed, each link has...
We build an efficient and reliable data transport protocol on top of the Short Message Service (SMS). We conduct a series of experiments to characterize SMS behaviour under bursty...
