چکیده
Wireless networks are increasingly deployed with the availability of inexpensive wireless network devices [blu, , Stemm et al., 1996]. These networks are power constrained since nodes operate with limited battery power. Therefore, there has been an increased interest in energy efficient communication protocols. This chapter gives a background on current research for energy efficient media access control (MAC) and routing protocols. This chapter is divided into two sections: Section 1.3-Energy Efficient MAC Protocols and Section 1.4-Energy Efficient Routing Protocols. Four MAC protocols are discussed in Section 1.3. Section 1.3.1 discusses the 802.11 protocol. Section 1.3.2 discusses the EC-MAC protocol. Section 1.3.3 discusses the PAMAS protocol. Finally, Section 1.3.4 discusses the Wave and Wait Protocol. Six routing protocols are discussed in Section 1.4. Section 1.4.1 gives a an analysis of the energy consumption of routing protocols. Section 1.4.2 discusses power aware routing in mobile ad hoc networks. Section 1.4.3 discusses localized power, cost and power-cost efficient routing algorithms. Section 1.4.4 discusses routing techniques used in Personal Area Networks (PANs) based on power related optimization and device information. Section 1.4.5 discusses routing techniques based on balancing nodes’ battery reserves in order to maximize the lifetime of the

A multiple criteria algorithm for planning the itinerary of mobile sink in wireless sensor networks
The mobile sink can increase the efficiency of wireless sensor networks. It moves in a monitored environment and collects the network nodes information. Thus, by the sink we can balance the power consumption and increases the network lifetime. Determining path of the sink's movement is usually modeled as an optimization problem where finding optimal solutions require collecting value of all the...

In indoor pico-cellular wireless systems, power is limited and therefore communication protocols need to be properly designed to conserve energy at the mobile stations. The existing schemes and heuristics to conserve power at the mobile devices by reducing the activity period of the mobile devices do not work effectively in a master driven TDD based systems such as Bluetooth. In this paper, we ...

متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
