RPL is an IPv6 routing protocol for low-power and lossy networks (LLNs) designed to meet the requirements of a wide range of LLN applications including smart grid AMIs, industrial and environmental monitoring, and wireless sensor networks. RPL allows bi-directional end-to-end IPv6 communication on resource constrained LLN devices, leading to the concept of the Internet of Things (IoT) with thousands...
The wireless communication technologies, such as wireless sensor network, can bring great economic benefits to industrial plants. But the open channel and multi-hop network topology will influence its real-time and reliable performance. Funneling effect is a kind of congestion caused by the wireless hop-by-hop and many-to-one networks. IEEE802.15.4 is a wireless personal area network standard that...
In this paper, we introduce a novel routing algorithm which is based on ant colony system. The objective of this novel algorithm is to solve the problem of energy and congestion control on wireless sensor network routing process. This novel algorithm is able to achieve better load balance and prolong the network lifetime. In this novel algorithm we combine the pheromone released by multi-ant colonies...
The sensor nodes in a wireless sensor network (WSN) are typically characterized by limited power supply, low bandwidth, small memory sizes and limited energy, leading to a very demanding environment to provide security. In this paper, we propose a protocol named fuzzy logic-based energy efficient packet loss preventive routing protocol (FEEPRP) that adopts a routing algorithm which imparts security...
For solving the issue of congestion in WSN (wireless sensor network), proposed a congestion avoidance and control mechanism for multiple paths routing protocol (MR-CACM), which integrates fairness, status of congestion and level of energy. Consequently the network can avoid congestion by assigning traffic to different paths. When congestion is occurred, it can help to detect congestion by using the...
A wireless sensor network consists of a large number of sensor nodes that are randomly deployed. This network is formed to perform the critical mission. The essential elements for the wireless sensor network are a source and sink. Source senses stimulus initiating a critical mission and transmits collected data to a sink. In the wireless network, the environment where a single sink and a large number...
