Route discovery and maintenance in Mobile Ad-hoc Network (MANET) is a problem of long standing interest. In ad-hoc networks the Ad-hoc on demand Distance Vector (AODV) protocol assumes that discovered route is optimal and transmits data on it for the entire data session, whereas due to dynamic topology nodes change position dynamically, the optimum route may change. Thus, node mobility may give rise...
Ad hoc On-demand Distance Vector (AODV) is an on demand routing protocol for delivering messages in a connected Mobile Ad hoc Network (MANET). AODV itself is an improved version of routing to maintain connection on demand and the route repair is the procedure that is called after the link expiration time. Connectivity in the network only exists when nodes are in radio range of each other. Routes can...
This paper has discussed some of the common mobility models and few uncommon ones and their impact on various networks and routing parameters. In the past, mobility models were rather casually used to evaluate network performance under different routing protocols. Therefore, the network performance will be strongly influenced by the nature of the mobility pattern. The mobility model plays an essential...
The link layer routing protocols 6lowpan ad hoc on-demand distance vector routing (LOAD) and dynamic MANET on-demand for 6lowpan (DYMO-low) are integrated in 6lowpan stack. The stack is less complicated and it support IPv6 enabled packets route for biomedical data. Both routing protocols are modified and developed new approach for patient healthcare monitoring system. Thus, proposed integration method...
A LoWPAN is a communication network that allows wireless connectivity in varies applications due to its unique advantages. LoWPANs can be benefit from IP and thus IPv6 networking formed. The combination of IP over LoWPAN is 6lowpan (IPv6 over low power wireless personal area networks). IP in WSNs can eliminate the need of translation gateway and other similar devices used in current WSNs. It allows...
Recent, technological advances in healthcare monitoring, sensors and wireless networking able to design a system for global healthcare monitoring applications such as ECG, SpO2, glucose, temperature etc. A 6lowpan (IPv6 low power wireless personal area networks) node with biomedical sensors strategically placed on the patient body area networks that can monitor biomedical data. The 6lowpan node has...
Ad-hoc wireless sensor network allows portable devices to establish communication independent of a central infrastructure within a USN. A lot of sensor nodes can move randomly due to un-centralized infrastructure. But it's faces numerous routing threats which adversely affect the success of important applications and gather information about physical phenomena. The current method is providing more...
