What is GPSR protocol?

ABSTRACT. We present Greedy Perimeter Stateless Routing (GPSR), a novel routing protocol for wireless datagram networks that uses the positions of routers and a packet’s destination to make packet forwarding decisions.

How does GPSR work?

GPSR is a geo routing method, which means that data packages are not sent to a special receiver but to coordinates. The packages should be relayed to the node that’s geographically closest to the coordinates. This assumes that every node knows its own position.

What is greedy forwarding?

Greedy forwarding tries to bring the message closer to the destination in each step using only local information. Thus, each node forwards the message to the neighbor that is most suitable from a local point of view.

What is selective forwarding?

In a selective forwarding attack (SFA), an attacker, which participates in the routing as normal node, selectively discards packets from neighboring nodes. … Some schemes adopt multi-path forwarding, in which multiple paths are used to route data to the sink node.

Which category is a negotiation based routing protocols in WSN?

The categories of routing protocols are network based organization, operation and route discovery. Most of the applications of WSN uses route discovery base routing protocols e.g. AODV, DSR & OLSR. The performance of these protocols is compared in different scenarios on the basis of throughput, delay and congestion.

How does tiny OS support concurrency?

TinyOS is fully non-blocking: it has one call stack. … While being non-blocking enables TinyOS to maintain high concurrency with one stack, it forces programmers to write complex logic by stitching together many small event handlers.

What is Leach protocol in WSN?

LEACH: the low energy adaptive clustering hierarchy protocol LEACH is a hierarchical routing protocol used in wireless sensor networks to expand the network lifetime. In the LEACH protocol, sensors arrange themselves in a cluster, and a single node of these nodes performs a cluster head.

What is WSN routing?

In WSN, routing is a very important task that is to be handled carefully. Routing technique is needed for sending the data between the sensor nodes and the base stations, so as to establish communication. … The routing problem leads to decreased network lifetime with increased energy consumption.

Why is TinyOS needed?

A primary goal of TinyOS is to enable and accelerate this innovation. Four broad requirements motivate the design of TinyOS: 1. Limited resources: Motes have very limited physical resources, due to the goals of small size, low cost, and low power consumption.

Is TinyOS real time?

The most popular and highly documented OS among the many is TinyOS. TinyOS has some limitations in terms of CPU scheduling, real-time applications support, etc. Because of the nonpreemptive First-Come-First-Serve policy of TinyOS the emergency jobs can’t get quick responses, and its node throughput decreases.
