This research is aimed to establish the small wireless sensor network under the real environment. The objectives this research is aimed to study the data transmission and evaluate the data transmission performance of RPL protocol in wireless sensor network. Four nodes of wireless sensor network have been installation and transmissions between nodes in single-hop and multi-hop have been simulation for testing and analyzing data from the network following the transmission performance index. The research found that the number of hop and building environment are the principle factor to the performance of RPL protocol this might be the major limit to implement the RPL protocol in wireless sensor network

The purpose of this research was to design and develop an internet management system using radius protocol for a school. The system was developed by PHP language MySQL database and radius protocol. It allowed an administrator to grant users permission to access the internet manage their accounts check their status and record their usage history in files in addition to teachers being able to limit the use of the internet in their classrooms. The system evaluation process was divided into two parts. First the efficiency of the system was evaluated by the administrator and it was found that the system can work as required. Second the system performance was evaluated in terms of network security functional requirement and processing speed by the completion of a questionnaire by five experts. User-friendliness was evaluated by the completion of a questionnaire by 115 teachers and students. Results showed that the average efficiency was 4.22 with a standard deviation of 0.07. It can be concluded that the effectiveness of the developed system was at a high level and its application was beneficial for other organizations

We present the comparison of CDMA MAC protocol with and without beat noise by using 2-D optical CDMA MAC protocol over WDM networks. We use the asymmetric primehop sequence code. Moreover we analyse the effect of the number of available wavelengths in tenns ofaverage number of attempted to transmissions per time slot (offered load) and beat noise is considered. The presented numerical results based on the throughput and delay time versus the offered load. We divide into two parts. The first one we consider the effect of the number of available wavelengths. Another is the effect of with and without beat noise in the 2-D OCDMA over WDM systems.

In this paper we have analyzed the performance of combining security system (SSL Protocol) with current TCP/IP module by porting security shareware into the EDC (Electronic Data Capture) devices. Finally in order to understand the impact on the EDC’s performance we test the throughput of the EDC before and after applying security with various encryption algorithms.
