Abstract
In a heterogeneous sensor actor network, packet loss may occur due to bad link quality, overflow of buffer, and low energy levels. Retransmission of the lost packets leads to more energy consumption and delay. Ensuring data reliability and minimum delay requirement while improving energy efficiency are challenging issues in a resource-constrained heterogeneous sensor actor network. In this paper, a fuzzy-based delay and energy-aware intelligent routing mechanism has been proposed to select efficient routes. In the proposed mechanism, routing decisions are taken using a fuzzy logic system by considering network resources, such as residual energy, quality of link, available buffer size, and distance (proximity). In a network, a node with higher residual energy, higher free available buffer, good link quality, and close distance (proximity) gets opportunity to become a next hop node in a routing path. Furthermore, network performance has been analyzed with various network states. Simulation has been carried out using Network Simulator 3 by considering performance metrics, such as delay, number of retransmissions, energy consumption, lifetime, and network stability of the network.
Highlights
Wireless sensor and actor network (WSAN) is a group of sensors and actors where a sensor node collects data by sensing operation and actors perform appropriate actions by processing the received data [1,2,3,4]
In WSANs, a data collection protocol may satisfy the major application requirements, such as high data reliability and less delay along with energy efficiency. ese requirements can be achieved by designing an energy efficient intelligent routing protocol. e sensor nodes may be deployed randomly in a dynamic environment [8]. is results in dropping of packets due to dynamic changes in quality of wireless links. e major reasons for dropping of packets may be bad wireless link quality and unavailability of free buffer at intermediate nodes and residual energy at nodes
The dropped packets need to be retransmitted, and this leads to more delay and energy consumption. erefore, an energy efficient routing protocol may solve the above issues by taking efficient routing decisions while considering energy of a node, link quality, and available buffer
Summary
Wireless sensor and actor network (WSAN) is a group of sensors and actors where a sensor node collects data by sensing operation and actors perform appropriate actions by processing the received data [1,2,3,4]. E major reasons for dropping of packets may be bad wireless link quality and unavailability of free buffer at intermediate nodes and residual energy at nodes. At means, selection of a node which has high available buffer, good wireless link quality, more residual energy, and close distance (proximity) as hop node reduces the packet dropping rate. A fuzzy-based intelligent delay and energy-aware routing mechanism has been proposed to improve the lifetime of the network. Available buffer, and quality of link and distance (proximity) are the primary considerable parameters to reduce the packet dropping rate at a node.
