“…In case no route is found, route discovery mode gets activated and it initiates a new route. OLSRv2 NIIGATA (Optimized Link State Routing, version 2 Routing Protocol) OLSRv2 (Liu et al, 2008) preserves has various enhancements on original OSLR protocol since basic protocol architecture is modular and flexible permitting security extensions as adds-on whereas OLSRv2 comprises of three basic processes: Neighborhood Discovery, MPR Flooding and Link State Advertisements. Neighborhood Discovery needs every router discover all other directly connected routers with one hop adjacency and checks for bi-directional transmission.…”

Medical sensors are implanted within the vital organs of human body to record and monitor the vital signs of pulse rate, heartbeat, electrocardiogram, body mass index, temperature, blood pressure, etc. to ensure their effective functioning. These are monitored to detect patient’s health from anywhere and at any time. The Wireless Sensor Networks are embedded in the form of Body Area Nets and are capable of sensing and storing the information on a digital device. Later this information could be inspected or even sent to a remotely located storage device specifically (server or any public or private cloud for analysis) so that a medical doctor can diagnose the present medical condition of a person or a patient. Such a facility would be of immense help in the event of an emergency such as a sudden disaster or natural calamity where communication is damaged, and the potential sources become inaccessible. The aim of this paper is to create a mobile platform using Mobile Ad hoc Network to support healthcare connectivity and treatment in emergency situations.

“…According to their proposal, bandwidth is shared between WiMAX subscriber stations and WiFi access points/routers but in our case, WiMAX serves as backhaul for WiFi's traffic. The study in [6] shows significant improvement of heterogeneous WiMAX-WiFi architecture over WiMAX or WiFi only architecture. Besides some fundamental differences in our scenario, our work compliments their findings by providing additional insights on the impacts of different (hexagonal) network topology designs, gateway-node radio, number of hops, and how to optimize node density towards supported data rates and user density.…”

Multi-tier, multi-hop network architecture with integrated WiMAX-WiFi radio interfaces offers an alternative means of delivering broadband wireless access services to mass users rapidly and cost-effectively. Besides providing wireless backhaul in places where wired backhaul infrastructure is not ready or too expensive, such architecture can also take advantage of the complementary features offered by the two diverse technologies. Such architecture however inspires a wide range of complex and interdependent design considerations covering network topology formation, number of radios per node, ratio between WiMAX and WiFi radio/node, number of hops at WiFi multi-hop tier and so on. This paper attempts to provide some insights on how different possible hybrid topology designs perform in terms of required node (WiFi access point/ WiMA Xbase station) density. In particular, we investigate how various designs scale towards two loading conditions namely the data rate per user and user density.

“…More closely related works to this paper have been studied to propose an intertwined packet routing and link scheduling scheme by solving an optimization problem in heterogeneous networks of Wi-Fi and WiMAX in [15]. Its formulation aims to maximize link utilization across multi-hop routing path using dual radio interfaces of Wi-Fi and WiMAX.…”

We present joint radio selection and relay scheme that delivers data from a source to a sink in heterogeneous stationary sensor networks consisting of various radio interfaces. The proposed scheme finds the optimal relay nodes and their corresponding radio interfaces that minimize energy consumption throughout the network while satisfying the end-to-end packet deadline requirement. We formulate the problem of routing through radio interface selection into binary integer programs, and obtain the optimal solution by solving with an optimization solver. We examine a trade-off relationship between energy consumption and packet delay based on network level simulations. We show that given the end-to-end deadline requirement, our routing algorithm finds the most energy-efficient routing path and radio interface across mesh hops. We demonstrate that the proposed routing scheme exploits the given packet delivery time to turn into network benefit of reducing energy consumption compared to routing based on single radio interface.
