Wireless sensor network consists of micro electro-mechanical sensor nodes which are operated by battery power. Sensor nodes lose energy for computation and communication. It is very difficult to recharge their battery as they are deployed in a remote place. Thus, power efficient routing in wireless sensor network is the main challenge for researchers. Hierarchical routing is one of the efficient techniques...
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...
In this paper, we introduce a novel algorithm for weighted-fair rate control, which solves congestion problems in wireless sensor networks. The goal of our algorithm is to achieve adaptive fairness both between nodes and between different weighted flows in one node for tree-based communication in wireless sensor networks. In theory, WFRCA is an efficient algorithm.
