In wireless ad hoc networks such as mobile ad hoc networks and sensor networks, most of the functions (routing, mobility management, and security) must rely on cooperation between nodes. Every node in these networks is both end host (it generates its ...

The severe energy constraints of sensors and the unique characteristics of underwater sensor networks (UWSNs) present major challenges for the long-term monitoring applications. This paper proposes two novel adaptive transmission algorithms for UWSNs to ...

In the wireless sensor networks, prolonging network lifetime is an important aim. Unbalanced energy consumption influences the network lifetime greatly. First this study proposes probability based energy balancing algorithms. A hybrid transmission ...

Prolonging the lifetime is an important design consideration for battery powered wireless sensor networks. In a network with stationary sink, the sensor nodes located near the sink have to relay data from the rest of the network and thus deplete their ...

This paper concerns routing performance in lossy wireless networks with Rayleigh fading channel. We investigate the efficiency of a few representative deterministic and opportunistic routing protocols under light-loaded traffic conditions. This work ...

The temporary and unfixed physical topology of a wireless adhoc network is determined by the distribution of the wireless nodes as well as the transmission power (range) assignment of each node. This paper studies asymmetric power assignments for which ...

Topology control is one of the most elementary topics in wireless sensor networks. Typically, most of the research only considered the bidirectional communication and symmetric weighted communication model, while the real wireless world contains not ...

Connected Dominating Set (CDS) has been a well known approach for constructing a virtual backbone to alleviate the broadcasting storm in wireless networks. Current research has focused on minimizing the size and diameter or improving the fault tolerance ...
