In this letter, we propose a new energy-efficient metric for relay node selection in multi-hop random wireless sensor networks (WSN) where the sensor nodes are distributed randomly and the node circuit energy consumption is also taken into consideration. During the routing, the relay node is selected in a forwarding area, which is defined by two parameters: a forwarding area radius and forwarding...
The system capacity of a cellular wireless system consisting of a large number of fixed location base stations (BSs) and random location mobile stations (MSs) is studied. Assuming that the BSs in a multi-cell system are connected to a centralized controller which has access to channel state information (CSI), it is possible to optimize transmissions such that capacity is maximized. This paper discusses...
