Time Saving and energy consumption has become a vital issue that attracts the attention of researchers in Underwater Wireless Sensor Networks (UWSNs) fields. According to that, there is a strong need to improve MAC protocols performance in UWSNs, particularly enhancing the effectiveness of ALOHA Protocol. In this paper, a time-saving Aloha protocol with slotted carrier sense proposed which we c...

As wireless networks become an integral component of the modern communication infrastructure, energy efficiency will be an important design consideration. Since batteries provide limited power, a general constraint of wireless communication is the short continuous operation time of mobile terminals. Therefore power management is one of the most challenging problems in wireless communication, an...

| This paper describes a MAC protocol called DSA++ that allows the full integration of mobile ATM terminals into an ATM network by extending the statistical multiplexing from ATM multiplexers on the air interface, ooering capacity on demand. The DSA++ protocol ooers functions necessary for the implementation of a resource scanning algorithm and power saving mode in the mobile station as well as...

The use of directional antennas in wireless ad hoc networks can significantly improve global performance due to a high spatial channel reuse. Nevertheless, its introduction poses new location dependent problems related to the MAC protocol. In this paper, the Balanced Incomplete Block Design theory has been exploited to develop a new MAC protocol for wireless ad hoc networks using directional ant...

The classical TCPilP layered protocol architecture is beginning to show signs of age. In order to cope with. problems such as the poor manager ~ performance of wireless links and mobile terminals, including the high error rate of wireless network interfaces, power saving requirements, quality of service, and an increasingly dynamic network environment, a protocol architecture that considers cro...

Wireless Sensor Networks (WSNs) are used in different civilian, military, and industrial applications. Recently, many routing protocols have been proposed attempting to find suitable routes to transmit data. In this paper we propose a Fuzzy Energy Aware tree-based Routing (FEAR) protocol that aims to enhance existing tree-based routing protocols and prolong the network’s life time by considerin...

This paper presents a power saving technique for multi-hop ad hoc networks. Our protocol uses a virtual backbone for energy conservation and routing. We propose a variable history based sleeping time for the non coordinators. Our simulations indicate that this scheme offers more power savings in a network with sparse message density than most other schemes discussed in the literature. We also p...

In this paper, we propose an approach to saving power by more aggressively using sleep mode. The sleep duration is estimated by measuring the on-line traffic information, i.e. slot utilization. A considerable amount of power can be saved by using the approach. Our approach does not use any additional signaling channel, nor does it need any overhead in the involved protocol. The algorithm is rea...
