-In wireless sensor network,sensor nodes has limited energy and communication ability due to which it is important to design a routing protocol.Routing protocol helps to increases network lifetime of wireless sensor network. This paper contains various existing routing protocol techniques. Keywords—WSN,LEACH,TEEN.APTEEN, location-based routing protocol

This paper describes a set of network metrics are helpful to predict behavior malicious node in wireless network. The Network and internet is the device which multiple people can communicate with each other through wired or media. Nowadays, Internet Things, Mobile, vehicular, ad hoc networks all merge into one shared These often used send receive confidential data information. unauthorized misu...

The availability of low-cost network interface cards (NICs) has made the IEEE 802.11 medium access control (MAC) protocol the de facto MAC standard for wireless mobile ad-hoc networks. Although the IEEE 802.11 MAC protocol is designed to have stations share a single channel in a network, many of the IEEE 802.11 physical (PHY) layer standards define multiple channels and allow the simultaneous, ...

In this paper a secure error-signalling scheme for packetswitched network architectures is presented. Current solutions are based on the Internet Control Message Protocol to deliver information regarding congestion control. The disadvantages of ICMP are given, regarding its limitations and dependence on network protocol structures. We then move into presenting the Future Core Network System, fo...

IPv6 is a network layer protocol of the OSI reference model. IPv6 uses the Neighbor Discovery Protocol (NDP) that works on link local scope of IPv6 network. NDP covers host initialization and address auto configuration that is one of IPv6 advantages and other important functionalities. IPv6 mandates to support Internet Protocol Security (IPSec) for end‐to‐end communication security. However, th...

We have successfully designed an efficient Simple Network Management Protocol (SNMP) for the monitoring, management and control of low cost Wireless Sensor Network (WSN). SNMP is a very popular protocol for network management in an IP based network. But since its packet fields are very much variable so it requires Type Length Value (TLV) encoding before transmission, which increases its size co...

Implementations of network protocols, such as DNS, DHCP and Zeroconf, are prone to flaws, security vulnerabilities and interoperability issues caused by developer mistakes and ambiguous requirements in protocol specifications. Detecting such problems is not easy because (i) many bugs manifest themselves only after prolonged operation; (ii) reasoning about semantic errors requires a machine-read...

The context of this paper and the corresponding challenges are formed by network services and their requirements to the underlying protocol stack. The relevance of this research is confirmed by three recent trends in network services and their execution environment: growing reliance of businesses and individuals on network connectivity, highly dynamic network characteristics, and a wide range o...

A secure time synchronization protocol (STSP) for wireless sensor network based on uTESLA protocol is proposed according to the issues that DCS algorithm in wireless sensor network time synchronization is limited in the threats of compromised nodes, big communication cost and deficiency in coverage. Firstly, initializing the network topology based on LEACH protocol to balance the network node l...
