Modified Simple Network Management Protocol for 6Lowpan

Abstract

Simple Network Management Protocol (SNMP) is an internet standard protocol for managing devices on IP network and is one of the key components of NMS (Network management system). It is also used in a variety of application such as remote monitoring and controlling of the network nodes. Lowpan consist of large number of low-cost devices.lowpan faces several challenging issues such as small packet size, low bandwidth, low power, a large number of devices. In order to, overcome these issues, the 6lowpan was originated. The 6lowpan group has defined encapsulation and header compression mechanism that allow,ipv6 packets to be sent to and received from over lowpan based networks.6lowpan is a severely resource constrained network. Hence, existing SNMP protocol need to be modified. The 6lowpan-snmp is an extended modification of the SNMP.The SNMP is mainly used to manage a sensor node which has allocated IP address. These IP networks can be integrated with the 6lowpan by transmitting the SNMP packets over 6lowpan.this can be achieved by compressing SNMP packet and reduce the number of SNMP message over the network. This paper, tries to show effectiveness and feasibility of the proposed scheme on resource-constraint sensor network.
