On-demand routing protocols use route caches to make routing decisions. Due to frequent topology changes, cached routes easily become stale. To address the cache staleness issue i...
— We consider a queueing system with controllable service rate; for example, a transmitter whose rate can be controlled by varying the transmission power. For such a system we ob...
— Estimation of network proximity among nodes is an important building block in several applications like service selection and composition, multicast tree formation, and overlay...
— We study hybrid search schemes for unstructured peer-to-peer networks. We quantify performance in terms of number of hits, network overhead, and response time. Our schemes comb...
— One of the challenges facing the networking industry today is to increase the profitability of Internet services. This calls for economic mechanisms that can enable providers ...
