    [Show abstract] [Hide abstract] ABSTRACT: A link quality estimation based routing protocol (LQER) is proposed to meet the high reliability of transmitting data in water environment monitoring in wetlands based on (m,k)-firm link quality estimation. It considers both energy efficiency and link qualities when the route is selected, which makes routing data more reliable and decreases the probability of retransmission, thus saves the energy and prolongs the lifetime of the whole network. Simulation results show that LQER can meet the requirements of energy efficiency, reliability and scalability for water environment monitoring in wetlands

    [Show abstract] [Hide abstract] ABSTRACT: Many routing protocols have been proposed for wireless sensor networks in recent years. For some special applications, not only energy aware but link reliable is needed. Historical link status should be captured while making routing decisions. In this paper, we design a reliable link quality estimation based routing protocol (LQER), which integrates the approach of minimum hop field and (m, k). The performance of LQER is evaluated by simulation experiments to be more energy-aware, with lower loss rate and better scalability than MHFR (Z. Ma and Y. Sun, 2004) and MCR (F. Ye et al., 2001). Thus the whole network may obtain longer lifetime and better link quality

  • [Show abstract] [Hide abstract] ABSTRACT: A multitude of applications of wireless sensor networks require that the sensor nodes be location-aware. Range-based localization schemes are sometimes not feasible due to hardware cost and resource restriction of the sensor nodes. As cost-efficient solutions, range-free localization schemes are more attractive for large-scale networks. This paper presents Weighted Centriod (W-Centriod), a novel range-free localization scheme extended on the basis of Centroid scheme, which takes received signal strength indicator (RSSI) metric into account besides connectivity metric used in Centroid scheme. It's shown that our W-Centriod method outperforms Centriod scheme significantly in terms of both the average localization error and the uniformity of error distribution across different positions, which decrease by 49.3% and by 37.7%, respectively, under the best circumstance. Moreover, a two-phase localization approach consisting of a field data collection phase and an off-line parameter optimization phase is proposed for localization in wireless sensor networks.

    [Show abstract] [Hide abstract] ABSTRACT: In this paper, we propose a scalable energy efficient medium access control protocol (SEMAC) based on time division multiple access (TDMA) technique for wireless sensor networks (WSNs), which uses the local information in scheduling, eliminates most collisions, is more energy efficient and is scalable to the number of sensor nodes in WSN. SEMAC uses the concept of periodic listen and sleep in order to avoid idle listening and overhearing. To balance the energy used in the whole network, SEMAC lets the node with lower energy be a winner in an election procedure based on their energy levels and the winner has more chances to sleep to save energy. We also use a clustering algorithm to form clusters so as to increase the scalability of SEMAC. The performance of SEMAC is evaluated by simulations, and the results show the gain in energy efficiency and scalability.

    [Show abstract] [Hide abstract] ABSTRACT: Recent advances in wireless sensor networks (WSN) have led to many new protocols specifically designed for different kinds of applications where energy efficiency is an essential consideration. Most of the attention, however, has been given to the medium access control (MAC) protocols since they pay an important role in wireless communications and traditional MAC protocols are not suitable for WSN. This paper tries to survey recent energy efficient MAC protocols for WSN and presents a classification of the various approaches pursued. The four main categories explored in this paper are scheduling based, collision free, contention based, and hybrid schemes. Several energy-efficient MAC protocols are described and discussed under the appropriate category. Moreover, requirements for the MAC layer in WSN are also discussed. The paper concludes with open research issues in the end.
