During last two decades, Mobile Ad hoc Networks (MANETs) has been in widespread use. However, in some critical applications such as in battlefield or area sensing, due to the node mobility, limited power and sparse deployment density, MANETs may suffer network partitioning. Without a stable end to end path, these challenged scenarios could cause most existing ad hoc networks protocols to fail. In...
In this paper, we propose a power-aware routing protocol with low route requests that finds a path with high path bandwidth. To have low routing requests, mobile nodes help to broadcast the routing request only when they first receive the routing requests. In addition, based on the receipt of the routing requests from the neighboring nodes, a mobile node records the location information of its one-hop...
The term MANET describes distributed, mobile, wireless, multihop networks that operate without the benefit of any existing infrastructure. When several nodes are participating in the mobile ad hoc network collision of packets may happen and sending the time bounded packets to the destination node is difficult. Different nodes can use the same bandwidth simultaneously as long as they are sufficiently...
This paper presents the design of a MESH network to provide services simultaneous of voice, video and data. The network architecture is constituted by two access points(APpsilas), two mobile wireless routers (WRpsilas), a mobile unit, a portable unit and a control center. The network was implemented at Instituto Politecnico Nacional (IPN), campus Zacatenco. We make different communications tests of...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
An ad-hoc network is the cooperative engagement of a collection of mobile nodes without the required intervention of any centralized access point or existing infrastructure. A number of routing protocols have already been proposed for ad-hoc networks. In most of these protocols, routing tables and considerable routing overheads are used to achieve routing. This paper proposes an approach to eliminate...
