In this paper, we introduce a novel algorithm aiming at maximizing the transmission capacity in wireless sensor networks (WSNs). Based on the Dijkstra algorithm and the max-flow theorem, the proposed algorithm solves the contradiction between the path length and forwarding capacity of various nodes, and thus scales up the relay capacity in terms of the number of transmitted packets from the source...
WirelessHART, an international standard of wireless industrial networks, adopted the concept of graph routing to meet the requirements of short latency and high reliability. However, WirelessHART networks also require longer network lifetimes when implemented for industrial applications. Designing a reasonable form of graph routing is one method to achieve a balanced consumption of network energy...
Due to the limitation, such as low computation, low calculation and limited energy, wireless sensor networks (WSN) usually have some vulnerabilities, such as data overflow, 0-divides etc. This paper designed a MAC Layer Tester (called MLT) based on fuzz and border conditions algorithm to detect vulnerabilities according to IEEE 802.15.4. MLT can test protocols stack for IEEE 802.15.4, such as ZigBee...
In wireless communication, the cooperative communications technology has been concern because of its advantages of spatial diversity. In particular, cooperative communication with a single relay is a simple, practical technology for wireless sensor networks. In this paper, we analyze several simple network topologies. Under the condition of equal power allocating, the optimum relay locations are respectively...
Although numerous routing protocols have been designed for wireless sensor networks, not all are suitable for wireless sensor networks in home automation (WSNHA). In this paper, we evaluate some popular wireless sensor network routing protocols for their suitability to WSNHA. We also propose a greedy-algorithm heuristic routing (GAHR) protocol and an A* algorithm for route finding. We compared the...
