Abstract

Wireless technology makes any devices can be connected without wire that limiting the range. We need an optimal placement and configuration of the access point for optimal coverage reasons. Signal strenght from access point does effect to a connection quality. Nowadays network analyst are using a network coverage analyzer software called Ekahau Heatmapper. It uses heatmap method to mapping network coverage. The software analyzes RSSI's (Received Signal Strenght Indicator) value then the value into a range. Each range is represented by color that signs the strenght of wireless signal. But its procedure should be awkward for some reason. You need to draw a sketch of the room that you want to analyze. Then you must bring your laptop to track around the room. Wi-Spec offers an alternatives with a same method based on heatmap that Ekahau Heatmapper does. Wi-Spec is a device using Wemos D1 as it's microcontroller with RGB Led Strips as output. We combine this method with light painting photography using a photo as frame makes the result is more real and accurate than info from 2D sketch that Ekahau does. Wi Spec compatible with Arduino IDE using ESP8266Wifi.h and FastLED.h. FasLED.h library features predifined color that can subtitute the heatmap color from Ekahau Heatmapper. These colors are : Green, Lime, , Yellow, Orange, Red, and running dot red light while it hasn't receive signal.. From the SSID and RSSI capability test, the device can't get the SSID and RSSI from a hidden configured SSID. Differences of wireless receivers beetween implementation caused a different result on one of an area point.

Abstract

Load balancing is a technique to divide the workload on 2 or more servers when there is a request from the client. In load balancing techniques there are several algorithms,, others: least connection, weighted least connection and others. This research uses weighted least connection algorithm. The weighted least connection algorithm divides the server load based on the weight value. The supporting tool for load balancing is IPVSADM with Piranha interface. In the test, the measured parameters are throughput, response time and CPU usage. The tool used in the test in httperf. From the test results with delivery of 10000 connections obtained by sending connections per second more will increase the throughput value. On testing the highest throughput value is 547,74 KB / s. Compared with the response time response, if given a high connection will be higher in the sense of slowing down. In connection distribution testing, the server with the highest weights accommodates more connections of 4000 connections, the lowest weight of 1000 connections from the total 10000 connections. In CPU usage testing, the weighted least connection algorithm is at least better than the least connection algorithm when applied to a heterogeneous server.

Abstract

Wireless Mesh network (WMN) is a set of wirelessly connected nodes forming a mesh topology. Over the WMN, the process of transmitting data information requires a path to get to the destination node, namely reactive protocol and proactive protocol. Security wise, routing protocols are still vulnerable to various forms of attack, especially against active attacks that can destroy, modify and deleting not only data but also the information within. Based on the said problems, the writer decided to make a research called Comparative Impact Analysis of Black Hole Attack on the Performance of OLSR and AODV routing Protocols in Wireless Mesh Network's Network. The results obtained in this study is that the black hole attack does affects the performance of AODV and OLSR routing protocols. The test was done using OMNET++ with three test scenarios, that is to say, without-attack; with multiple-attack nodes; and with big-probability of attack. Test parameters include throughput, end-to-end delay, packet loss and packet delivery ratio. The result of research using 18 nodes of attacker showed that packet loss on OLSR is higher than AODV which is proved by the highest packet loss result in AODV that only has 99.33% while OLSR has 99,50%.
