  ABSTRACT: Based on the empirical studies of approximate linear correlation between transmission power and link quality, we propose a multi-power opportunistic routing scheme with network coding for wireless sensor networks. A new routing metric taking energy consumption and link quality into account is defined, and an optimal transmission power and forwarding set selection algorithm is implemented, which is used to establish lowest-cost paths from each node to sink. The algorithm extends Dijkstra's algorithm and has a polynomial-time complexity. Intra-session network coding method is also employed in the routing process where we propose a distributed forwarding control and quota assignment algorithm to minimize the transmissions of coded packets. Moreover, a novel picking strategy of coding coefficients greatly decreases the header overhead of small size of sensor data packets. Extensive experiments on TinyOS-Mote based testbed show that the routing approaches perform up to 85% better on energy efficiency than MORE with a fixed transmission power.

• Conference Proceeding: Adaptive Distributed Randomized TDMA Scheduling For Clustered Wireless Sensor Networks

  ABSTRACT: This paper presents an adaptive distributed TDMA slot assignment algorithm, called A-DRAND, which is an improved version of DRAM) in clustered wireless sensor networks where cluster heads need more slots and will be alternated afterwards by other cluster members for energy balance reason. It utilizes cluster info to allocate slots discriminately for different kind of sensor node and adapts its operation depending on the requirements of the application. The overhead is reduced significantly by reserving a special slot number range for slot reassignment. Simulation results show that running time and transmission cost of slot reassignment is only at most 1/m of that of all-participating assignment, where m is the proportion of cluster heads and other sensors with changing slots demanding in the network.

• Conference Proceeding: Cluster-Based Multi-Path Data Dissemination Scheme for Large Scale Wireless Sensor Networks

  ABSTRACT: Acquiring critical events for mobile or static sinks poses great challenges for applications of wireless sensor network in emergency response and other surveillance scenarios. In this paper, a clustering-based multi-path data dissemination scheme (CMPDD) is proposed. The cluster head and several dissemination nodes in each cluster collaboratively process data and deliver data to multiple mobile/static sinks with good energy efficiency and lower delay. Adapting to varying number of source-sink pairs, one or multiple paths are set up for event dissemination between sinks and sources. Reliability is enhanced by backup mechanism among dissemination nodes. Simulation results show that this scheme outperforms TTDD in energy consumption, transmission delay and resilience to node failures.
