This paper introduces I-MAC, a new medium access control protocol for wireless sensor networks. I-MAC targets at improving both channel utilisation and energy efficiency while taking into account traffic load for each sensor node according to its role in the network. I-MAC reaches its objectives through prioritized and adaptive access to the channel. I-MAC performances obtained through simulations...
In this paper, we consider the multiple sinks placement problem in large-scale wireless sensor networks (WSN). The objective is to determine optimal sinks' positions that maximize the network lifetime by reducing energy consumption related to data transmissions from sensor nodes to different sinks. Balanced graph partitioning techniques are used to split the entire WSN into connected sub-networks...
This paper presents the design, implementation and evaluation of an extensible software data path for a programmable router. The objective is to provide a configurable, dynamic and flexible software router architecture to enable service deployment at run time. The router forwarding plane uses the forwarding element (FE) model provided by the forwarding and control element separation (ForCES) architecture...
