This paper proposes two architectures, including an Opportunistic Large Array Concentric Routing Algorithm with Geographic Relay Nodes (OLACRA-GRN) architecture, and an Opportunistic Large Array Concentric Routing Algorithm with Relay Nodes (OLACRA-RN) architecture. First, the OLACRA-GRN architecture with the geographic information of relay nodes reduces node energy consumption and finds the optimum...
In this paper, we proposed a multi-hop distributed energy-efficient clustering with sub-clustering (MHDEEC-SC) architecture. Our architecture selects a fitter node served as cluster head, and uses the concept of sub-clustering that chooses a node in remote areas with higher energy to serve as sub-cluster head. Besides, our architecture can balance the energy consumption between nodes and improves...
To solve the location issue, in this paper, we proposed a Received Signal Strength for Directional Antenna (RSS-DA) scheme, it uses the mobile anchor nodes that already know the coordinates to join the Received Signal Strength (RSS) measurement in the data transmission. The number of beacons conforms to the terminated threshold in the sensor nodes, the estimated locations are used the RSS algorithm...
In wireless sensor networks (WSNs), the sensor nodes are randomly deployed, and energy is limited. Energy consumption reduction is therefore very important. To extend the system lifetime, we used the intersection-based coverage algorithm (IBCA) to address lifetime, its introduction causes sensor nodes to enter sleep mode when not operating. This algorithm can achieve reduced energy consumption in...
In Wireless Sensors Networks (WSNs), energy efficiency is an important topic. To prolong the lifetime and achieve effective geographic routing, we apply a sparse number of anchors and color theory to estimate location of sensor nodes. In this paper, we modify the election of relay node which differs from Color-theory-based Energy Efficient Routing (CEER) algorithm. This approach can reduce the transmission...
In this paper, we propose a novel algorithm which combines fuzzy logical control (FLC) and Taguchi method to select the optimal cluster heads from a wireless sensor network (WSN). In a WSN, FLC algorithm is used to select cluster head and to reach the energy consumption balance among all nodes, which can in turn decrease the probability of the early death of the nodes. In addition, the equation of...
This paper proposes a novel energy efficient data clustering scheme to improve energy efficiency for cluster-based wireless sensor networks (WSNs). In order to reduce the energy dissipation of transmitting sensing data at each sensor, the fixed clustering algorithm uniformly divides the sensing area into clusters where the cluster head is deployed to the centered of the cluster area. Moreover, to...
