Mobile Ad Hoc Networks (MANETs) are groups of mobile nodes which can be formed randomly and dynamically without network infrastructures beforehand. One of the challenges of research in MANETs is constant topology changes which make initially efficient network become inefficient. AODV routing protocol and DSDV have a flaw in their mobility network such as an increase in routing overhead. It causes...
Routing protocols play important roles in mobile adhoc network performance. The Protocols find and decided the communication path with the routing algorithm to deliver the data along the networks. Channel qualities in wireless communication are an important factor in network performance. Previous research in routing protocol development did not much pay attention in this matter. This paper shows the...
In the future, Community Health Center (PUSKESMAS) spread throughout Indonesia is expected to play an important role in improving public health. Currently, the government still has obstacles in monitoring the readiness level of PUSKESMAS service and conditions. This research is aimed at creating a prototype, web-based geographic information system (WEBGIS) with the polygon method. This application...
In the future, mobile ad hoc network (MANET) is predicted to play more important roles for device communication with self organized infrastructure. Effectiveness of routing protocols and congestion control mechanisms, highly determines the performance of MANET. Previous research in protocol development did not pay much attention in selecting the appropriate protocol on other layers. Therefore, the...
In optical network survivability, link-based and subpath-based restorations have been discussed in many papers as survivability methods for optical wavelength division multiplexing (WDM) network. One of the problem in both restoration methods occurs when network resources are unavailable. In such condition, the traffic is dropped and the source node is requested to retransmit the packets. This paper...
Important factors that support the quality of communication in wireless ad hoc networks are routing and congestion controls. The protocols had many challenges in wireless ad hoc network such as high bit error, frequent changes of routing path, as well as limitations of power and bandwidth. To improve the performance of wireless ad hoc network, cross-layer optimization methods are currently gaining...
Routing mechanism is one of the many ways to optimize the performance of Zigbee network that used battery-powered device. Therefore, a variety of routing algorithms are developed to obtain the optimal performance. One of the examples is Power-Source Aware Routing (PSAR) algorithm. However, PSAR algorithm has problem that the reconfiguration of battery powered node from communication path is not always...
Puskesmas (health centers) is one of the spearheads of health services to the community in Indonesia. Through Puskesmas, government could provide health care and run the program for public health at the same time. But people have problems in accessing information about the existence and health services in Puskesmas. Besides that, the government also have difficulties to monitor the level of service...
Femtocell is one of the micro base station technologies, use low power levels and operates in licensed spectrum and connected to the Internet with backhaul networks, which is used to expand the coverage and increase capacity, and the installation is auto configuration. The basic of this technology is due to the difficulties of mobile user to get the best signal from base station, one of them is the...
Future of mobile adhoc network (MANET) is predicted grow due to the capability of network manage independently. One of important role in this network is routing protocols. A number of research about algorithm to find the best path in transmit of data has been done. Some routing protocol used in MANET, such as AODV, DSR and DSDV. This paper presents about investigation result of AODV, DSR and DSDV...
In recent years, several TCP congestion control algorithms have been proposed to increase the ability of TCP in high-speed and long distance networks. One of TCP implementations, which in MANET, opened new challenges for those algorithms to demonstrate the stability, scalability, and efficiency of the mechanism. This paper compared two TCP congestion control algorithms, namely Cubic TCP and Yeah TCP...
Nowadays, technology tends to be developed to wireless technology. One of factors affects that development is mobile capability offered by the system to users. One of current wireless technology is mobile ad-hoc network. Important feature of mobile ad-hoc network implementation is routing protocol such as AODV and BATMAN. Implementing AODV and BATMAN in real life is by using AODV UU and BATMAN Daemon...
Mobile Adhoc is a network that does not have the infrastructure and have the ability to manage its network independently, in the future this network predicted to be the key to the development of network applications. Routing protocols have an important role in this network, a lot of research has been done. In this research we use optimized routing protocols in mobile ad hoc network (MANET), the optimization...
