Tactical Networks is typical Ad Hoc Network. Its structure leads to relative fixation for hierarchy and clustering. In order to maintain the cluster stabilization and network function in particular cases, Group leader election can be reached by address list message and connectedness message.
Wireless sensor and actuator networks (WSANs) are used for longterm observation and monitoring. Such long-lasting deployments require different maintenance tasks, such as the replacement of nodes — motes, and the most critical initial installation of the sensor nodes. We propose the algorithm of the self-organization for wireless sensor and actuator networks, which determines the productivity of the...
In wireless self-organized network (WSON), AOW clustering algorithms can achieve better performance and high adaptability, but having limitations in certain circumstances. In this paper, working procedure and shortcomings of AOW are introduced and analyzed firstly. Then, several modified algorithms based on AOW are designed according to system requirements. Simulation experiments are conducted to...
Energy is one of the most constraining factors in wireless sensor networks and node failures due to crash and energy exhaustion are commonplace. In order to avoid degradation of service due to faults, it is necessary for the WSN to be able to detect faults early and initiate recovery actions. In this paper, we propose a decentralized method for fault detection and recovery in clustered wireless sensor...
Wireless Sensor networks (WSN) are inherently fault-prone due to the shared wireless communication medium and harsh environments in which they are deployed. Energy is one of the most constraining factors and node failures due to crash and energy exhaustion are commonplace. In order to avoid degradation of service due to faults, it is necessary for the WSN to be able to detect faults early and initiate...
In wireless sensor networks, the size of backbone network have a great impact on communication overhead, as well as the network lifetime. It can be designed based on cluster tree. MIS (maximum independent sets) composed of clusterheads is achieved by clustering algorithm, based which MCDS(minimal connected dominating sets) and MST(minimum spanning tree) are built with improved Prim algorithm, and...
In wireless sensor networks, the data-centric sensing task focuses more on the data reliability. In this paper, a reliable clustering algorithm RCVC (reliable clustering using virtual cluster-head) is proposed. It provides multipath for nodes in the network by using a set of redundant cluster-heads which are marked with a unique virtual identification. When the active cluster-heads fail, according...
Hierarchical routing is a promising approach for point-to-point routing with very small routing state. While there are many theoretical analyses and high-level simulations demonstrating its benefits, there has been little work to evaluate it in a realistic wireless sensor network setting. Based on numerous proposed hierarchical routing infrastructures, we develop a framework that captures the common...
