The construction method used by detection engine Snort-NG based on ID3 decision tree has the problem of excessive memory occupancy. The idea that the test properties are chosen according to the gradation of rule property in network protocol stack was presented in this paper; that is, the property of link layer first determined, and then network layer and transport layer. The atomicity of the value of these properties were preserved and the values of these properties were treated as a whole. The results of experiment showed that the occupancy of memory was much less in the state of non-trivial property being very common with this approach.

Wireless sensor network consists various sensor nodes that are used to monitor any target area like forest fire detection by our army person and monitoring any industrial activity by industry manager. Wireless sensor networks have been deployed in several cities to monitor the concentration of dangerous gases for citizens. In wireless sensor network when sensor nodes communicate from each other then routing protocol are used for communication between protocol layers. Wireless sensor network protocol stack consist five layers such as Application layer, Transport layer, Network layer, MAC Layer, Physical layer. In this paper we study and analysis Bellman-Ford routing algorithm and check the flow of data between these protocol layers. For simulation purpose we are using Qualnet 5.0.2 simulator tool.

Modbus is a popular network protocol in the industrial manufacturing environment. A modbus communication stack requires two layers:the modbus application protocol which defines the data model and functions and a Network layer. The FreeMODBUS provides an implementation of the modbus application protocol and supports RTU/ASCII transmission models. The paper introduces the analysis of FreeMODBUSs whole framework and the serial links implementation. According to the analysis, it is easily to realize the modbus protocol stack on the chip which FreeMODBUS hasnt realized and so quickly to finish the product design.

AbstractOne of the use of VOIP and IPTV technology that is increasingly used as a communication application on the internet are video call and video streaming, so when the data required a reliable and fast protocol performance in the process of delivery. The problem of the research is analyzing the performance of layer transport protocol in VOIP and IPTV data traffic. The objective of the research is to know the advantages and disadvantages of VOIP and IPTV data traffic and it is useful to contribute to the development of transport layer protocols in VOIP and IPTV data traffic in the future. This research is conducted independently without related to place and time. This reasearch uses SoftPerfect network Protocol Analyzer software. SoftPerfect network Protocol Analyzer is used to compare the performance of transport layer protocols of TCP, UDP, SCTV based on six parameters using different LAN and Wireless cable, test time, and sharing time. The method used in this research is based on the research approach. The results of this study indicate that SCTV protocol is a protocol that has good performance in VOIP and IPTV data traffic with TCP and UDP protocol.Keywords : Analysis, Performance, TCP, UDP, SCTP, VOIP, IPTV

Routing uses a unique identifier of each participating node in the network to forward the information between two nodes. Traditionally, routing takes place at the network layer of a standard network layering architecture where it takes into account the local or the global network information, albeit, the local information uses a local-scope unique identifier. One of the prime objectives of any routing strategy at the network layer is to forward data from one end to another; however, the same objective can also be achieved at the data link layer by using the hardware address of each node as a unique identifier. This chapter discusses the key questions. (i.e., Why traditional routing is called IP-based routing? What if we reorient the traditional concept of routing on the data link layer? What are the positive and negative impact, to carry out routing at IP—or data link—layer?) This study may be helpful for researchers to understand the concept of IP-based routing and path selection at link layer regardless of the standard layering architecture and the type of IP address.


In this design unit, a design to test the performances of varying models was developed for the simulations in the PLC-base data link layer. The design includes a smart home and a Smart Grid environment where a comparison between Zigbee and WiMax-based models can be performed. The Smart Grid Test Bed has been designed using OPNET and Power Line Communication is proposed in this book. It is being designed to allow test bed experiments in four layers among OSI 7 layers. This chapter is organized as follows: The Physical Layer and Datalink Layer for Smart Grid Test Bed in Section 1; the Transport Layer for Smart Grid Test Bed in Section 2; and finally, Application Layer for Smart Grid Test Bed in Section.
