Many low-energy MAC and routing protocols have been proposed for Wireless Sensor Networks (WSNs) since reducing energy consumption is a primary concern to meet the requirements of practical applications. Reducing delivery delay is, indeed, another promising requirement in WSNs because a large part of applications of WSNs intends to watch the sensed objects in real time although the amount of allowable delay differs according to cases. In this paper, we deal with a class of receiver-initiated MAC protocols, which is a promising energy-efficient MAC mechanism, and propose to schedule beacon timings so as to reduce the delivery delay of data packets. The key idea is to schedule beacon timings in the sequence of distance from leaf node to the sink node and reduce the time of packets staying at each node. Specifically, each sensor node selects a time slot to send beacon in a distributed manner based on their distances (i.e., hop counts) from the sink node, and autonomously adjusts its beacon timing to avoid frame collisions. Computer simulations show that the proposed protocol can collect data in a shorter time with less energy consumption than the conventional receiver-initiated MAC protocols.

ZigBee is a recent wireless networking technology built on IEEE 802.15.4 standard and designed especially for low-data rate and low-duty cycle applications such as home and building automation and sensor networks. One of the primary goals of ZigBee is low power consumption and therefore long-living networks. Despite this goal, current network formation and routing protocols described in the ZigBee specification do not fully address power consumption issues. In this work, we propose a distributed routing algorithm to reduce power consumption of battery-powered devices by routing the communication through mains-powered devices whenever possible and consequently increasing the overall network lifetime. The proposed algorithm works on tree topologies supported by ZigBee and requires only minor modifications to the current specification. Our ns-2 simulation results showed that the algorithm is able to reduce the power consumption of battery-powered devices significantly with minimal communication overhead.

In [40,41], some image transmission and retrieving systems for WMSN are proposed. In [40], an experimental setup is established to transmit several example images from source nodes to sink over both real testbed and simulation.…”

Wireless multimedia sensor networks (WMSNs) have an increasing variety of multimedia-based applications including image and video transmission. In these types of applications, multimedia sensor nodes should ideally maximize perceptual quality and minimize energy expenditures in communication. For the required perceptual quality to be obtained, qualityaware routing is a key research area in WMSNs. However, mapping the system parameters to the end user's perceptual quality-of-service measures is a challenging task because of incomplete identification metrics. Unfortunately, unless disputable assumptions and simplifications are made, optimal routing algorithm is not tractable. In this paper, we propose a novel image transmission framework to optimize both perceptual quality and energy expenditure in WMSNs. Our framework aims to provide acceptable perceptual quality at the end user by using an analytical distortion prediction model that is able to predict the image distortion resulting from any given error pattern. The innovation of the proposed scheme lies in the combined use of a content-aware packet prioritization with an energy-aware and quality-aware routing protocol, named as image quality-aware routing. Additionally, it does not only propose an energy-efficient route selection policy but also manages the network load according to the energy residues of nodes, thus leading to a great energy economy. The results reveal that the framework is capable of identifying true metrics for mapping required image quality to network parameters.
