An optimal logical topology of a wireless sensor network (WSN) facilitates the deployed sensor nodes to
communicate with each other with little overheads, lowers energy consumption, lengthens lifetime of the
network, provides scalability, increases reliability, and reduces latency. Designing an optimal logical
topology for a WSN thus needs to consi...

... among the sensor nodes are restricted to only the successive sensor nodes. Figure 10 shows the communication pattern inside a chain. In this figure, six sensor nodes (C 0 to C 5 ) construct a chain. ...
Context 2
... information and control messages are propagated hop-by-hop from one sensor node to its successive neighbouring node. For example, Figure 10(a) shows that the leader node C 2 sends the control information to the nodes C 1 and C 3 . After copying the control message, the node C 1 sends the control message to the node C 0 and C 3 sends the message to C 4 , which then sends it to C 5 . ...

... sending the sensed data, each sensor node sends data to its successive node towards the leader of the chain. For example, in Figure 10(b), the node C 0 sends its sensed data to the node C 1 , while the node C 1 merges its own data with C 0 's data, and sends them to the leader node C 2 . Similarly, the node C 5 sends its data to the node C 4 , C 4 then sends C 5 's data and its own data to the node C 3 . ...

The wireless sensor networks suffer from the problem of energy consumption, so it has been used several protocols to avoid this problem, the best of these protocols is a LEACH protocol which works to reduce the energy consumption of the network. On the other hand, LEACH protocol suffers from the problems of accelerated the dead nodes as well as the...
With the expansion of smart agriculture, wireless sensor networks are being increasingly applied. These networks collect environmental information, such as temperature, humidity, and CO2 rates. However, if a faulty sensor node operates continuously in the network, unnecessary data transmission adversely impacts the network. Accordingly, a data-base...
Priority packet scheduling algorithms of Wireless Sensor Networks (WSNs) are different for real-time and non real-time data packets, at sensor nodes main constraint is reducing the energy consumption and transmission delay. Existing algorithms of packet scheduling in WSNs are pre-emptive scheduling, non-pre-emptive scheduling, First Come First Serv...
The paper mainly focuses on the methods for improving accuracy of energy prediction using piggybacking technique. Generally, the sensor nodes send their energy/location information to the Base Station (BS). BS then applies suitable clustering technique to group the nodes in clusters and declares the list of CGs and CMs. Afterwards, the CHs and CMs...
Research on wireless sensor network (WSN) has mainly involved the use of a portable and limited power source, namely batteries, to power the sensors. Without energy, a sensor is essentially useless and can not contribute to the utility of the network as a whole. As a result, considerable research effort has been devoted to designing energy efficien...

... Based on the fact that "energy is the main consideration in analysing routing protocols in WSNs" [18], chain-based routing protocols are considered to be more promising than other routing protocols approach due to its primary ability and feature in power saving and extending network lifetime [13,19]. ...
The main objective of routing protocol is to select the next-hop connection node for packets traveling from source to distention. Greedy algorithm depends on the distance only to select the next-hop connection and it is building one chain only. Delay is considering the main drawback in all chain based routing protocols in the wireless sensor network. Direct Line Routing Protocol (DLRP) is a proposed protocol in this scientific research and it has three phases which are intraconnection, interconnection and chain head selection. DLRP connects all sensor nodes in the same line (column) in one chain then selects one node as the chain head (CH) to connecting directly with the base station (BS). CHs in DLRP have lower responsibility for data delivery than other protocols that make energy saving and avoid data redundancy. Network simulator 3 (ns-3) is used to evaluate the performance of DLRP including all phases with close routing protocols DCBRP and CCM since they are for deterministic node deployment and in the same experimental environment. The results show the superiority of DLRP based on related performance metrics which average end-to-end delay, power consumption, CHs power consumption, and delay*energy metrics. Furthermore, DLRP can adopt to another deployment method to increase the stability and prolong the lifetime of the Network.
