Wireless mesh network (WMNs) can replace the physical existence of wired network; nevertheless, to solve the problem of traffic and congestion, they must carefully arrange radio resource assignment. In this paper, we focus on the major issues while transferring the data over the network and optimization of resources. WMN mainly suffers from congestion problem when numbers of channel transfer data at a same time which indirectly leads to overlapping channels and sometime data cannot be mitigated to destination. To overcome this problem and provide optimal solution we proposed hybrid channel assignment technique which offers four phase solution technique, in this technique firstly by mitigating the traffic than assigning the optimal path based on greedy and BFS. The purpose of this congestion control hybrid ant based greedy-BFS-load balancing (CCHAGBL) technique is to diminish the number of used slots, which is directly related to the overall resource assignment. We also provide optimal solution using Ant colony optimization technique with hybrid algorithm to achieve the network efficiency and resource utilization with randomly generated traffic. With the help of hybrid ant based greedy-BFS-load balancing (GBL) channel assignment algorithm throughput and packet delivery ratio is upgraded and delay is reduced to minimum.

“…In the proposed framework, idle channels were allocated according to the QoS requirements of users, which improved the spectrum utilization. Sathyasri et al 5 proposed the Enhanced Traffic-Aware Channel Assignment Protocol helping the mesh nodes present in the large-scale mesh networks to assign the channels. Jagannath et al 6 proposed a cross-layer routing and spectrum allocation algorithm based on the deadline for the sake of QoS requirements.…”

The quality of service (QoS) is a momentous performance index of wireless ad hoc networks. However, unreasonable channel allocation will degrade the QoS. During the process of channel allocation, if user requests for idle channels are rejected, the QoS will lower accordingly. In this paper, we propose a dynamic channel allocation strategy for QoS enhancement to enhance the QoS and reduce the rejection rate of idle channel requests. First of all, the channel availability model is modeled as a Continuous Time Markov Chain in a bid to calculate the channel availability which is used to compute the channel availability factor (CAF) and the channel availability threshold (CAT).Then, the dynamic channel allocation process is achieved based on the comparison result of CAF and CAT. Ultimately, the QoS is guaranteed by exploiting the earliest deadline first algorithm to forward packets and enhanced by using the packet segmentation algorithm to divide packets into packet flows. The simulation results prove that the proposed channel allocation strategy increases the packet delivery ratio and throughput, decreases the end-to-end delay and total overhead and shows a QoS enhancement than existing schemes. K E Y W O R D Schannel allocation strategy, channel availability, QoS, wireless ad hoc network INTRODUCTIONWireless ad hoc network is composed of mobile nodes communicating with each other via wireless links without central node and fixed infrastructure support. It has a broad application prospect in the field of military communication and disaster relief due to the merits of data forwarding through relay node and self-healing function. Multi-interface multichannel wireless ad hoc network allows mobile nodes to share multiple common channels. Therefore, mobile nodes can send and receive the packets at the same time which can reduce the delay and improve the throughput. The quality of service (QoS) parameters include the packet delivery ratio, throughput, end-to-end delay, and total overhead. 1 QoS enhancement means the increase of packet delivery ratio and throughput and the decrease of end-to-end delay, and total overhead. However, irrational allocation of shared channels brings about request rejection, routing failure, and other problems, which will increase the end-to-end delay and total overhead and reduce the QoS. Therefore, how to design a sound dynamic channel allocation strategy and enhance QoS have drawn extensive notices.Channel allocation depends on the number of accessible frequency channels and the time slot of the available channel. In the existing literature, researchers have put forward different channel allocation strategies. Karaoglu and Heinzelman 2 made a research on the on-demand dynamic channel allocation mechanism suitable for nonuniform load in mobile ad hoc networks (MANETs) and creatively proposed a lightweight dynamic channel allocation mechanism (LDCAM) and a cooperative load balancing strategy. The interference level was proposed as the basis for channel allocation

<p>Underwater sensor networks (UWSNs) are recently recognized as a promising method for monitoring and exploring the underwater environment. Due to real-time remote data monitoring requirements, UWSN has become a preferred network to a large extent. But reliable and efficient secure data transmission to the receiver is one of the most important challenges for UWSNs, often suffer from irreplaceable batteries and high latency for long-distance communications. The most challenging task is extending network life, shortening transmission distances for each node. Thus, this paper presents the reliable efficient cluster routing (RECR) protocol, optimal shortest path finding (OSPF) algorithm and hill transformation data encryption (HTDE) algorithm for UWSNs. The proposed encryption algorithm encrypts the data from the source node, and the RECR protocol is used for reliable data delivery from source to destination. To extend the network's life, RECR employs autonomous underwater vehicle (AUV) from the sink node (SN) for data collection. The OSPF algorithm is used to find the shortest path for data transmission to avoid latency. The proposed RECR protocol, HTDE and OSPF algorithm enhance the secure data transmission efficiency, minimizing the energy consumption and improves the network life time. The proposed protocol decreases end-to-end latency, packet loss.</p>
