This paper aims to compare several location-based routing protocols in wireless sensor networks. Although location-based routing protocols have apparent limitations, it can support multi-hop data transmission. In addition, location-based routing protocols need to consume a lot of energy to transmit location information.

In today's world, with the rise in the count of vehicles and lack of proper navigation, the congestion has become a major problem. In this scenario, VANETs play a very important part in improving the traffic condition and also in providing proper navigation. Improved navigation system reduces congestion thereby reducing the possibility of occurrence of accidents. In this research work, we have used a position-basedrouting protocol i.e., GPSR (Greedy Perimeter Stateless routing Protocol) to effectively analyze the geographical position of the vehicles in the network and to provide updated navigation information. In this system, we have used a security mechanism to identify valid and invalid messages for secure V2V and V2I communications. This mechanism drops all the invalid messages thereby keeping the VANET secure. It also reduces the possibility of attacks on wireless communications in the VANET. This system has better safety features and network performance compared to other hybrid schemes via NS2 simulation.

Wireless Sensor Networks (WSNs) can be engaged in various type of applications such as environmental, biomedical and military etc. One of the primary objectives of WSNs would be to perform data communication while attempting to increase the life of the wireless network and protecting it against connectivity collapse by using effective energy management approaches. Various challenging factors influence the design of routingprotocols for WSNs. These factors needs to be addressed and overcome in order to accomplish effectual communication in WSNs. In this paper we have presented a survey regarding the locationbasedroutingprotocols. The paper includes the suitable application for each protocol moreover it includes the comparison of different locationbasedprotocols with respect to power consumption, scalability, path selection metric etc.
