Efficient MAC protocol has been paramount importance for improving the performance of WSN. In this paper, Boarder Node Medium Access Control (BN-MAC) mobility aware hybrid protocol is introduced for WSN. BNMAC controls overhearing, idle listening and congestion problem to save energy. BN-MAC mechanism is based on novel semi synchronous low duty cycle that takes less time for accessing channel a...

Sensor networks in underwater environments face unique adverse conditions. In order to be functional, specialized routing protocols are required to route the data from source to destination. This paper surveys routing protocols for underwater sensor networks. The routing protocols are examined and compared with respect to the network conditions and quality measures such as packet delivery ratio...

While decentralized medium access control (MAC) protocols are more popular in wireless networks, cluster based sensor networks are particularly amenable to centralized, polling based protocols. This paper presents an analytic model to evaluate the performance of a polling based MAC protocol in terms of the packet delay, buffer overflow rates and energy consumption. We show that the polling base...

There are many technical challenges for designing large-scale underwater sensor networks, especially the sensor node localization. Although many papers studied for large-scale sensor node localization, previous studies mainly study the location algorithm without the cross layer design for localization. In this paper, by utilizing the network hierarchical structure of underwater sensor networks,...

This paper describes and analyzes a novel MAC protocol named distributed-control polling (DCP), which has been designed to bring together the most interesting features of distributed-control MAC protocols (e.g., DQDB) and centralized token-passing MAC protocols (e.g. , FASNET, FDDI, EXPRESS-NET). From the fully distributed MAC protocols, DCP acquires the capability to guarantee both a complete ...

This paper investigates a multi-mode MAC protocol suite for use in a heterogeneous underwater network. Modems from different manufacturers may employ different physical layers and MAC protocols. If multiple modems operating in the same or overlapping frequency bands are deployed in the same geographic area, they cannot function correctly due to interference. We propose a mechanism to achieve co...
