WSN-Wireless Sensor Network Following are the features of WSN:

• WSN is a network which is made of large number of sensor nodes known as sensor motes. This nodes are self directed and low powered devices.

• These nodes collect, process and convey the data to users.

• The WSN nodes perform less computing and processing.

• The nodes are energy efficient.

• WSN need infrastructure and has large number of nodes in hundreds or thousands.

Ad hoc Network

Unlike WSN, ad hoc network do not require any infrastructure and has less number of nodes. Following table mentions features of Ad hoc network and mentions difference between wireless sensor network(WSN) and Ad Hoc network types.
