Requirement for high bandwidth internet traffic is growing rapidly now-a-days. Utilization of the available resources becomes troublesome due to rise in the number of users. So it is important to provide the resources efficiently. To solve the problem of resource provisioning, many developments have been made by the researchers. During working hours, the scheduled traffic is huge and sluggish during...
Requirement for high bandwidth traffic has been increasing very rapidly. Efficient and effective provisioning of resources is very important now-a-days. Due to the increase in number of users, providing sufficient bandwidth has become a difficult task for the service providers and network operators. Researchers have developed many techniques to resolve this issue but they have not reached to full...
In this paper, a health care system is described for rural areas considering a small village using hybrid network i.e. which operates both in ADHOC and cellular region. In this system, a small village is considered in which sensors are attached to people, the whole area is divided into clusters. The sensors considered for this system can operate in both ADHOC and GSM region. In each cluster, a sensor...
In this paper, an efficient routing protocol for patient monitoring system in rural areas was proposed using wireless sensor network (WSN) so that the patients can be treated within less time. In this system, a village with GSM network is considered and the people in that village are continuously monitored using AMON sensor, an advanced medical monitoring and alert system. All the AMON's work in ADHOC...
The paper describes an Energy — Efficient Resource Allocation protocol for Wavelength-Routed All-Optical WDM Networks. Protocol selects efficient and low power consumption optimal primary and backup paths. The path selection will be done by Central Management System (CMS). The selection will be by two methods, i.e., the path with less number of free wavelengths will not be considered for selection...
Ad Hoc wireless network is a type of wirelessnetwork, in which there is no any fixed infrastructure. Devices in Ad Hoc network can move around thenetwork within a given range. Currently most of thetransactions are performed through the computernetworks so they are more susceptible to many physicalsecurity threats. One of the major DOS Attacks thatdegrade the performance of the whole MANET is BlackHole...
Existing methodologies in WDM networks, generally uses either lightpath distance or network congestion to identify optimal and backup lightpaths. In our paper, we have designed an efficient alternate RWA protocol (EARP) which considers both congestion and route distance so as to improve the network performance. On arrival of a request the source node sends control signals through all the paths to...
In this paper we present the design of an Advanced Centralized RWA Protocol (ACRP) in which the cost of a lightpath is computed based on its number of available free wavelengths and number of wavelength conversions. Centralized Management System (CMS I) assigns optimal primary and backup lightpaths. CMS II updates the optimal primary and backup lightpaths as and when the number of free wavelengths...
Balancing the load among multiple path leads to the degradation in the all-optical WDM networks. It is always desirable to deliver the entire load on a single optimal path depending upon the current network load status. This paper employs the use of ant colony optimization (ACO) for routing and wavelength assignment (RWA) problem of all-optical WDM networks along with survivability. Our algorithm...
