TL;DR: This review paper mainly concentrates on the study of different protocols that are used for efficient energy consumption using the mobile sink and mobile sensor nodes.
Abstract: Sensor network is made up of a large number of sensor nodes for communication. Some nodes can work as a gateway which transmits data to the sink. These nodes are considered as a bottleneck in multi-hop networks because they send data collected from other nodes, and hence it drains their energy quickly. This problem is known as Hot Spot problem. So, for balancing the energy throughout the network, sink and node mobility can be used. A mobile sink could collect data without the need of gateway, and hence the problem of a bottleneck in the multi-hop network can be minimized. Along with the sink, sensor nodes also can be made mobile. Energy efficiency of WSN is achieved by using mobile sensors and mobile sink with enhanced coverage, and better channel capacity. There are various routing protocols to reduce energy consumption in a mobile WSN. This review paper mainly concentrates on the study of different protocols that are used for efficient energy consumption using the mobile sink and mobile sensor nodes.

TL;DR: This paper proposes an enhancement to an existing protocol for accommodating node mobility through neighboring node information while keeping the utilization of resources to a minimum.
Abstract: In wireless sensor networks, the routing algorithms currently available assume that the sensor nodes are stationary Therefore when mobility modulation is applied to the wireless sensor networks, most of the current routing algorithms suffer from performance degradation The path breaks in mobile wireless networks are due to the movement of mobile nodes, node failure, channel fading and shadowing It is desirable to deal with dynamic topology changes with optimal effort in terms of resource and channel utilization As the nodes in wireless sensor medium make use of wireless broadcast to communicate, it is possible to make use of neighboring node information to recover from path failure Cooperation among the neighboring nodes plays an important role in the context of routing among the mobile nodes This paper proposes an enhancement to an existing protocol for accommodating node mobility through neighboring node information while keeping the utilization of resources to a minimum

TL;DR: This proposed research concentrates on measuring the gas level of air contamination around the cities and reduces the man power and also increases the overall flexibility of sender and receiver.
Abstract: Wireless Sensor Network (WSN) plays an important role in the application of environmental monitoring. Mostly air pollution being major issues as cause many hazardous effects on ecological system of human being. Therefore the need of monitoring air pollution around the city and the public transport buses and cars are very important problem today. Basically, environmental monitoring methods have difficulties in wired sensor network but by using WSN it is possible to achieve the challenging issues by implementing internet/intranet. This proposed research concentrates on measuring the gas level of air contamination around the cities and reduces the man power and also increases the overall flexibility of sender and receiver. The main objective of the proposed system for the moving vehicles is monitor the NO2, Humidity, Temperature, CO levels of air contamination by using NO2 sensor, Humidity sensor, Temperature sensor, CO sensor. In our proposed work MANET(Mobile Ad Hoc Network) routing algorithm is used which has nearly 28 mobile nodes(Vehicles) provide a coverage area of 300meters around the city. The sensor data of the vehicles will be sent to the smart phones of the appropriate drivers to monitor effectively. The result of the proposed method includes the following parameters such as data type, speed of transmission, coverage of system, coverage area size, and No.of vehicles to closely monitor the proposed system.

TL;DR: A novel energy efficient routing protocol for wireless sensor networks in which the sensor nodes as well as the base station are mobile and the re-clustering time and energy has been minimized by introducing the concept of cluster head panel.
Abstract: In this paper, we present a novel energy efficient routing protocol for wireless sensor networks in which the sensor nodes as well as the base station are mobile. The protocol is hierarchical and cluster based from network structure perspective. Each cluster contains one cluster head node and two deputy cluster head nodes. The re-clustering time and energy has been minimized by introducing the concept of cluster head panel. Some simulation results are shown which depict the energy efficiency and prolonged life time of the nodes under the influence of the proposed protocol. Future scope of the work is outlined.

TL;DR: Simulation results show that BEENISH, MBEENish, iBEenISH, and iMBEENISH protocols outperform contemporary protocols in terms of stability period, network lifetime, and throughput.
Abstract: In this paper, we propose Balanced Energy-Efficient Network Integrated Super Heterogeneous (BEENISH), improved BEENISH (iBEENISH), Mobile BEENISH (MBEENISH), and improved Mobile BEENISH (iMBEENISH) protocols for heterogeneous wireless sensor networks (WSNs). BEENISH considers four energy levels of nodes and selects cluster heads (CHs) on the base of residual energy levels of nodes and average energy level of the network, whereas iBEENISH dynamically varies the CHs selection probability in an efficient manner leading to increased network lifetime. We also present a mathematical sink mobility model and validate this model by implementing it in BEENISH (resulting in MBEENISH) and iBEENISH (resulting in iMBEENISH). Finally, simulation results show that BEENISH, MBEENISH, iBEENISH, and iMBEENISH protocols outperform contemporary protocols in terms of stability period, network lifetime, and throughput.

TL;DR: The performance of LEACH- Mobile protocol is evaluated and compared with the LEACH protocol based on metrics such as energy consumed, number of alive nodes, packet delivery ratio and packet loss.
Abstract: and centralized LEACH has demonstrated the possibility of achieving good efficient routing path for wireless sensor network. By taking into consideration the mixed sensory fields with fixed and mobile nodes in a sensor field LEACH and LEACH-C are not appropriate to support mobile sensor nodes. The enclosure of mobility as a new criterion for the cluster creation and maintenance adds new challenges for these clustering schemes. The Mobile LEACH protocol is suitable for mobile wireless sensor networks, which provides a highly adaptive routing scheme to deal with clusterhead selection and frequent topology changes. In this paper the performance of LEACH- Mobile protocol is evaluated and compared with the LEACH protocol based on metrics such as energy consumed, number of alive nodes, packet delivery ratio and packet loss.
