In this paper, we propose two routing protocols for Terrestrial Wireless Sensor Networks (TWSNs); Hybrid Energy Efficient Reactive (HEER), and Multi-hop Hybrid Energy Efficient Reactive (MHEER) routing protocol. The main purpose of designing these protocols is to improve the network lifetime and particularly the stability period of the underlying n...
Article
In this paper, we select three most widely used reactive protocols; ad-hoc ondemand distance vector (AODV), dynamic source routing (DSR) and dynamic manet on-demand (DYMO), and model their energy and time consumption costs of expanding ring search (ERS) algorithm in wireless multi-hop networks (WMhNs). A novel contribution of this work is tuning th...
Article
The nodes in wireless sensor networks (WSNs) contain limited energy resources, which are needed to transmit data to base station (BS). Routing protocols are designed to reduce the energy consumption. Clustering algorithms are best in this aspect. Such clustering algorithms increase the stability and lifetime of the network. However, every routing p...

In this paper, a framework is presented for node distribution with respect to density, network connectivity and communication time. According to modeled framework we evaluate and compare the performance of three routing protocols; Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Fisheye State Routing (FSR) in MANETs and VAN...

In recent years, interests in the applications of Wireless Body Area Sensor Network (WBASN) is noticeably developed. WBASN is playing a significant role to get the real time and precise data with reduced level of energy consumption. It comprises of tiny, lightweight and energy restricted sensors, placed in/on the human body, to monitor any ambiguit...
Article
Wireless Body Area Sensor Network (WBASN) is a technology employed mainly for patient health monitoring. New research is being done to take the technology to the next level i.e. player's fatigue monitoring in sports. Muscle fatigue is the main cause of player's performance degradation. This type of fatigue can be measured by sensing the accumulatio...
Article
In this work, we propose a reliable, power efficient and high throughput routing protocol for Wireless Body Area Networks (WBANs). We use multi-hop topology to achieve minimum energy consumption and longer network lifetime. We propose a cost function to select parent node or forwarder. Proposed cost function selects a parent node which has high res...
Article
Wireless Sensor Networks (WSNs) consist of numerous sensors which send sensed data to base station. Energy conservation is an important issue for sensor nodes as they have limited power.Many routing protocols have been proposed earlier for energy efficiency of both homogeneous and heterogeneous environments. We can prolong our stability and network...

... Multi-hop HEER-Sink Mobility (MHEER-SM) [135] is an upgraded version of HEER algorithm, which combines three operations, a fixed number of clusters, multi-hop routing for distant cluster heads, and a mechanically driven sink. MHEER-SM separates the network area in sub-areas with equal numbers of nodes that operate as clusters, performs the HEER's cluster head election process, and efficiently monitors all the areas. ...
... Packet 0 is already ready to be processed for routing. There are several parameters such as IP precedence, DSCP, buffer size etc are exploited by RED based on which the packets are dropped before congestion occurs [24], [25]. We take the concepts of these techniques and exploit the ML techniques to automate the parametric setup of routing protocols of MANETs. ...
... Moreover, iAM-DisCNT is aided with linear-programming-based mathematical models for data flow maximization and packet drop minimization. Here, it is important to mention that section ''The proposed protocol: AM-DisCNT'' summarizes our previous work in Rao et al. 11 and section ''Extending AM-DisCNT: iAM-DisCNT'' includes the improvements made to our previous work. ...
... Mobility prediction is nothing but the estimation of their future locations of the node. There is few mobility prediction methods are proposed in literature [6,7]. The main advantage of mobility prediction is to allocate in advance, the convenient another access point (node) before If the mobile terminal leaves the present one, for reducing the interruption that is in the communication taking place between the terminal mobiles. ...
... The complexity is minimal since the two layers in this second method are distinct. [13] introduces the SIMPLE protocol for WBAN, where parent node, or forwarder, with the highest residual energy and the closest proximity to the sink is chosen using a cost function. Nodes having a lower cost function value are chosen to be parent nodes. ...
... Other sensors transmit their data to the sink through the forwarder node and follow their parent node. Distance Aware Relaying Energy Efficient (DARE) is introduced by A. Tauqir et al. [14] to monitor patients in multi-hop Body Area Sensor Networks (BASNs). Through the use of on-body relays that are fastened to the chest of each patient, the sensors communicate with the sink to reduce energy use. ...
... Primarily, WBANs were established for providing healthcare services to serious patients at hospital or at home. Later on, WBANs were extended to continuously and also remotely monitor human body, for example, a player during sports, a soldier during war, and so on [10,[13][14][15]. ...
... Recently, several routing protocols have been proposed for increasing the lifetime of sensor networks by reducing the communication energy consumption. In [1], a hybrid energy-efficient reactive protocol was presented. To choose the head of the cluster, this protocol uses the ratio between residual energy for the nodes and average energy of the network. ...
