In this paper, we propose an energy-efficient command broadcast protocol based on the construction of a spanning tree which includes maximizing the number of leaf nodes, and the allocation of one sharable slot to each tree level. The sharable slot that allocates to tree level will be divided into multiple mini slots, and non-leaf nodes at the same level will compete for broadcasting; in this way, collision can be reduced.

This paper presents a slot-scheduled broadcast protocol (SSBP) that combines the strengths of the flooding and the sharable slot protocol [9] such that every node can generate its own sharable slot, making the sharable slot topology-independent.

In the Mobile Ad-hoc Network (MANET), there are several ways of attacking network operation bypassing fault routing information between malicious and normal nodes. It will degrade efficiency of the network so we cannot archive the purposes of the designed MANET.

In this paper, a new Raspberry PI supercomputer cluster architecture is proposed. Generally, to gain speed at petaflops and exaflops, typical modern supercomputers based on 2009-2018 computing technologies must consume between 6 MW and 20 MW of electrical power, almost all of which is converted into heat, requiring high cost for cooling technology and Cooling Towers. The management of heat density has remained a key issue for most centralized supercomputers.

In research topics to improve the performance of the mobile ad hoc networks (MANET), the load balancing routing has attracted many research groups because it is an effective solution to reduce traffic congestion. However, to balance the traffic load, the routing algorithm often has to choose some long routes. These routes pass through many hops and intermediate nodes, so the accumulated noise along with the route increases.

In this paper, we present a distributed and scalable evolutionary game played by autonomous mobile ad hoc network (MANET) nodes to place themselves uniformly over a dynamically changing environment without a centralized controller. A node spreading evolutionary game, called NSEG, runs at each mobile node, autonomously makes movement decisions based on localized data while the movement probabilities of possible next locations are assigned by a forced-based genetic algorithm (FGA).

Mobile Ad Hoc wireless Networks (MANETs) is defined as a multi-hop infrastructureless wireless network which is self-organized and connects two or more stations spontaneously in the absence of central point or any access point. It allows peer-to-peer connections between devices that are operating in ad-hoc mode and are within the wireless range. They can form standalone groups of wireless nodes and can be connected to a cellular or fixed network. Nodes in a mobile adhoc network are free to move and organize themselves in an arbitrary fashion.

It is well known that neighbor discovery is a critical component of proactive routing protocols in wireless ad hoc networks. However there is no formal study on the performance of proposed neighbor discovery mechanisms. This paper provides a detailed model of key performance metrics of neighbor discovery algorithms, such as node degree and the distribution of the distance to symmetric neighbors. The model accounts for the dynamics of neighbor discovery as well as node density, mobility, radio and interference.

In this paper, we will provide a survey of the various approaches to deal with power control management in mobile ad-hoc wireless networks. We will classify these approaches into five main approaches: (a) Node-Degree Constrained Approach, (b) Location Information Based Approach, (c) Graph Theory Approach, (d) Game Theory Approach and (e) Multi-Parameter Optimization Approach.

Peer-to-peer (P2P) networks existing on a MANET are a natural evolution since both are decentralized and have dynamic topologies. As MANETs grow in use due to the increasing popularity of wireless mesh and 4G networks, it is expected that P2P applications will remain as a popular means of obtaining files. Network coding has been shown as an efficient means of sharing large files in a P2P network. With network coding, all file blocks have the same relative importance.

TCP over wireless networks is challenging due to random losses and ACK interference. Although network coding schemes have been proposed to improve TCP robustness against extreme random losses, a critical problem still remains of DATA–ACK interference. To address this issue, we use inter-flow coding between DATA and ACK to reduce the number of transmissions among nodes. In addition, we also utilize a ‘‘pipeline’’ random linear coding scheme with adaptive redundancy to overcome high packet loss over unreliable links.

This paper investigates the problem of inter-cell interference (ICI) in Long Term Evolution (LTE) mobile systems, which is one of the main problems that causes loss of packets between the base station and the mobile station. Recently, different frequency reuse methods, such as soft and fractional frequency reuse, have been introduced in order to mitigate this type of interference. In this paper, minimizing the packet loss between the base station and the mobile station is the main concern.
