Abstract

Design of a Lightweight u-SNMP Agent

Management system can adjust piece of program each individual devices in the network

Underwater – Network Management System (U-NMS) can support underwater devices for

managing individually by an manager / u-agent program.

U-NMS can maintain u-MIB (MO, Object ID), etc.

The U-NMS can support manipulates data structure, which is defining in the MIB modules and

design UML diagram.

To enable the reliable IoT applications: Low power battery operated devices and different design tradeoffs have to be considered

both in hardware and software implementations IoUT can support Service & Device discovery, indeed dynamically change in devices integration

Finally, we should analyze several following factors:

Interconnection legacy NMS based on SNMP

Design of u-SNMP agent via UML

UML based modeling for the u-SNMP agent

u-SNMP architectural model


Basic idea for management station can dominate all request for the managed devices and sensors

via management operations on MIB objects

A lot of MIB modules can define more than 10.000 objects

Most of managed object (MO) can related to MIB and each MO has own unique number (OID)

The agent synchronously response to the manager (management station) based on request

Management protocol the u-SNMP consists of four basic operations (GET, GetNext, Set, and Trap)

The major advantages are designing and modeling UML agent and manager possibility

Introduction(1/2)



Network Management System (NMS) Ability of monitoring, management, and optimizing a network

Manager console Something is admin for adjusting whole of the system communication

Manager One of high level performance devices which has the capable of querying any managed device – via polling

Agent A program that is packaged within the network element A piece of software that is bundled with the network device

Device Management Database (DMD) Regularly store and contains standard set of statistical and control values defined from hardware nodes on a

network

Management Information Base (MIB) Collections of definitions which define the properties of the managed object within the device to be managed A collection of information which is organized hierarchically

Object Identifiers (OID) Uniquely identify managed objects in an MIB hierarchy

Managed Object(MO) Represent characteristics of a managed device Represent a physical entity, a network service, or an abstraction of a resource that exists independently of its

use in management

Introduction(2/2)



Managed devices need to be unique and secure in the network

The main difference is constrained management must be lightweight high level and low level API

IoT and U-IoT system possible to solve several issues during OID integrations

Problem statements and requirements:

Network Management cannot easily protect of the cloning ID;

The U-NMS shall require fault management, which detected and rectified before the

management station even becomes aware of it;

The U-NMS can belongs to detecting challenges such as link goes down, battery,

disappearing devices or another;

The management station uses the manager to communication agent through Ethernet or anothercommunication network.

Agent can use Device handler to conjunction with managednodes such as sensor, gateway, as so on.

In that case, for underwater sensor, actuator, gateway other related devices. Inside of themanagement, station has Device management database (DMD) which is related MIB files and otherimportant system information.

Important achievements in the paper is shown below:

1. Analysis of the MIB structure and deploy the private MIB

2. IANA and getting unique number (U-NMS)

3. SMI and ASN.1 for defining the MIB tree

4. U-NMS and process of manager and agent system

5. Underwater management protocol (like u-SNMP) and using this OID system

6. UML designing u-SNMP agent and manager integration

7. u-MIB designing structure

8. improving implementation process in the real testbed in underwater.
