The current de-facto routing protocol over WSN developed by IETF Working Group (6LOWPAN) named as Routing Protocol for Low Power and Lossy networks (RPL) [1], to enable IPv6 packets carrying over IEEE 802.4 and to empower the usage of IoT over WSN. Because of the potential large networks, number of nodes and the fact that multiple coexisting applications will be running in the same physical layer,...
In the WSN(Wireless Sensor Networks, WSN), part of the node failure will affect the normal operation of the entire network. In this article, we design a self-healing algorithm of cellular-type WSN through improvements of Flooding algorithm based on the frequency and distance, combining with cellular structure. The algorithm can send the failure information of the node in time and quickly organizes...
Energy efficient multicast routing is one of the fundamental problems in wireless sensor networks (WSNs). Previous work has shown that when the goal is to find multicast trees with minimum transmission cost, the problem becomes NP-complete. In this work, we present a heuristic distributed minimum transmission multicast routing protocol (MTMRP) for WSNs. By introducing the biased backoff scheme and...
We propose a novel clustered routing approach with the separation of path findings from data transfer in wireless sensor networks. The proposed protocol differs the traditional clustered routing in the following aspects: global communication adopts multi-hop mode, cluster heads are only responsible for path findings, and data are transmitted by gateways. The principal advantage of the proposed routing...
To the characteristics of energy limitation of wireless sensor networks, the author puts forward a WSN routing algorithm based on ant algorithm by analyzing and studying WSN routing protocol. In the algorithm, the former of the pheromone not only considers the gradient factor between the nodes but also integrates with the residual energy of notes. It can economize energy and prolong the whole network...
Intermittent connected mobile sensor networks (ICMSN) have emerged in recent studies, e.g. underwater sensor networks, wildlife tracking and human-oriented flu virus monitoring. In these networks, there are no end to end connections from sensor nodes to sink nodes due to low node density and node mobility. Therefore, conventional routing protocols in WSN are not practical for ICMSN since packets will...
This paper first converts the routing problem into linear programming problem of global optimization, and proves the equivalence between the routing problem and linear programming problem. On the basis of the above, the genetic algorithm (GA) is used for solving the routing problem about avoiding the energy-hole. By way of code of the routing scheme, this paper proposes a global optimal routing algorithm...
