In this paper we model and study the performance of peer-to-peer (P2P) file sharing systems in terms of their `service capacity'. We identify two regimes of interest: the tra...
Abstract. Ethernet and IP form the basis of the vast majority of LAN installations. But these protocols do not provide comprehensive security mechanisms, and thus give way for a pl...
Distributed Web-server systems have been widely used to provide effective Internet services. The management of these systems requires dynamic controls of the Web traffic. With the...
Wireless sensor networks (WSNs) are typically characterized by a limited energy supply at sensor nodes. Hence, energy efficiency is an important issue in the system design and op...
This work explores several system issues regarding the design and implementation of routing protocols for ad-hoc wireless networks. We examine the routing architecture in current ...
