Limitations of current multi-channel MAC protocols include requiring of strict time synchronization, existing large number of multi-channel hidden terminals, and lacking single-hop broadcast support and sleep mechanism, i.e. duty cycling. This paper proposes an asynchronous duty cycle based multichannel MAC protocol, called DCM, for wireless sensor networks. Instead of requiring time synchronization among nodes, DCM takes advantage of receiver-initiated cross channel handshake mechanism to make a channel reservation for data transmission, and employs receiver adjustment mechanism to tackle the problem of the loss of broadcasting data and to improve broadcast reliability. According to theoretical analysis using Queueing theory, this paper obtains the average number of available channels. The simulation and testbed experimental results show that DCM reduces the number of multi-channel hidden terminals effectively, and achieves significant improvement in network throughput with increasing benefit as traffic loads increase while maintaining higher energy efficiency.

In this paper, a multi-channel MAC protocol, called M&M, with multiple channel reservation is proposed to tackle the channel conflict problem. M&M is fully distributed with no requirements of time synchronization or multi-radio, so it is very practical to implement M&M in resource-constrained sensor nodes. M&M can make nodes to choose one actually idle channel for communications from all assumed idle channels. Therefore, M&M can greatly alleviate, if not completely eliminate, packet collisions resulted by the channel conflict, and thus conserve more energy to prolong the lifetime of WSNs. To investigate the values of multiple channel reservation, extensive simulation and real testbed experiments are conducted. The results show that when the number of channels becomes larger or loads are heavy, M&M improves energy efficiency and throughput significantly. © 2010 IEEE.

In this paper, the concept of multi-radio sensor networks is introduced, and the reliability for multi-radio MAC protocol is researched extensively, via establishing a probability model of reliability. To be specific, the reliability of MAC protocols for multi-radio nodes are studies from single-hop and multi-hop, respectively. Furthermore, the upper and lower bounds of these reliabilities are provided. Lastly, the performance rate between single-radio and multi-radio MAC protocols is proposed. The experiment results show that the reliability of multi-radio MAC protocols is much higher than that of single-radio MAC protocol. In addition, the experiment results roughly coincide with theoretical analysis. © 2010 IEEE.

In this paper, a duty cycle based multi-channel MAC protocol with multiple channel reservation, called M-cube, is proposed to tackle the triple hidden terminal problems. M-cube can make nodes to choose one actually idle channel from all the expected idle channels. Therefore, M-cube can avoid data packet collisions resulted by the triple hidden terminal problems. By minimizing the lower bound of the average number of times of channel switching in M-cube, the optimal duty cycle is obtained through theoretical analysis. To validate the effectiveness of multiple channel reservation and dynamic optimal duty cycling, extensive simulations and real test bed experiments were conducted. Both the simulation and experiment results show that when the number of channels is large or network loads are heavy, M-cube improves energy efficiency and throughput significantly compared with other works in the literature. © 2010 IEEE.

To handle the triple hidden terminal problems, this paper proposes OCO, an asynchronous multi-channel MAC protocol with opportunistic cooperation for wireless sensor networks. By adopting opportunistic cooperation, OCO effectively alleviates, if not eliminates, the triple hidden terminal problems. More importantly, OCO is fully distributed with no requirements of time synchronization or multi-radio scheme, so it is easy to be implemented on the real sensor nodes. Via the theoretical analysis, the opportunistic probability that a node cooperates with its neighbor is obtained. To validate the effectiveness of opportunistic cooperation, extensive simulations and real test bed experiments were con-ducted. The simulation and experimental results show that when the number of channels is large or the network loads are heavy, OCO improves energy efficiency and throughput significantly compared with other works in the literature.

Study on distributed channel allocation and routing forwarding strategy in Dual-Radio sensor networks

引用

Tongxin Xuebao/Journal on Communications 2010年第9 A期31卷 81-89页

作者： Fan, Bin Li, Jin-Bao Guo, Long-Jiang Liu, Xu Ren, Qian-Qian School of Computer Science and Technology Heilongjiang University Harbin 150080 China Key Laboratory of Database and Parallel Computing of Heilongjiang Province Harbin 150080 China

Considering the limited orthogonal channels in wireless sensor networks (WSN), a distributed channel allocation algorithm (DCA) for Dual-Radio WSN was presented. Based on DCA, a routing forwarding strategy (RFS) was proposed as well. DCA avoids conflictions within a path and reduces conflictions among different paths with a small number of channels. Furthermore theoretically prove that when K≥Δ+1, the upper bound of the network throughput is |M|+1, where K is the number of orthogonal channels in WSN, Δ is the largest degree of the network topology graph, and |M| is the number of non-leaf nodes in the network routing tree. Nodes switch channels timely in RFS, and then further dropping the conflict between the paths, effectively transmit data in parallel. Simulation results indicate that DCA and RFS can reduce the latency of data forwarding and the average energy consumption of nodes, as well as increase the throughput significantly.

Energy-efficient algorithm for mobile target prediction and tracking in wireless sensor networks

引用

Tongxin Xuebao/Journal on Communications 2010年第9 A期31卷 135-143页

作者： Liu, Xu Li, Jin-Bao Guo, Long-Jiang Fan, Bin Zhu, Jing-Hua School of Computer Science and Technology Heilongjiang University Harbin 150080 China Key Laboratory of Database and Parallel Computing of Heilongjiang Province Harbin 150080 China

Aiming at the problem of target tracking in wireless sensor networks, an energy efficient algorithm for mobile targets prediction and tracking was proposed. Sleep scheduling mechanism was used to reduce the cost, as well as to guarantee the real-time tracking. The algorithm predicts the trajectory of the target with the Markov chain theory, and the sleeping nodes in the predicted area would be waked up to monitor the targets. In order to predict the target accurately, a location algorithm based on distance vector was triggered to estimate its position. The sensors sleep initiatively to save energy when they did not have the sensing task. Simulation and testbed experimental results indicate that the algorithms can accurately describe the target trajectory, and efficiently reduce the energy consumption.
